Mouse not locking in Wine/Proton programs in fullscreen or windowed

[ardishko]

It seems like I've found a major bug that could push away a lot of people playing games on Hyprland, It's got to do with mouse locking. Every time I run a game under Wine or Proton, (might not be exclusive to Wine or Proton) after tabbing out for a while and tab back in, the mouse locking is broken. The cursor seems to be still moving. I have tested this under Sway to see if the same behaviour could be observed there and after my testing, I can say that this is exclusively Hyprland behaviour. This doesn't look like It's a Proton or Wine bug, I've tested a lot of games extensively under Sway and Hyprland and It looks like Hyprland has some problems to iron out

Test games were:
Deep Rock Galactic (Proton 7.0-6)
Overwatch 2 (Latest Wine-GE as of 27-05-2023) (DD//MM//YEAR)

Steps to Reproduce:

Open a game run with Proton or Wine
Switch to another workspace for a few minutes, maybe 10 if you want to be sure
Switch back to the game and have your mouse lock ruined

Expected Behaviour

For the mouse not to lose it's mouse locking properties after

Noted Outcome:

Mouse locking breaking after switching to a different workspace

Possible related bugs on the issue tracker:
#1732 (This issue is not the same as my mouse doesn't escape into my other monitor all the time but rather it looks like I am locked between certain regions while in-game which is caused by the mouse getting stuck on the edges of the screen.

It is also worth noting that a similar thing happens on Waydroid while trying to run Roblox on it, though it might be a function on Waydroid not working, since there are issues about that open the Waydroid's Github page too. (Can't test because this stopped working for me, will update if I can test)

[ardishko]

Just observed the same behavior whenever the game works normally, the mouse moves in the background but it does not escape the window, It plays normally. Not a problem but it seems like it's related.

I will attach a video when I can get some footage, OBS is acting up a bit.

See here: ValveSoftware/gamescope#196 (comment)
Others users report fullscreen applications don't capture the mouse on Hyprland. I haven't tried a native program.

Also, here is the log. I did quite a few things here so It's quite long. If a cleaner log would be better, let me know and I will log into Hyprland once again to ONLY open steam and launch a game. https://n0paste.tk/mTp0Y54/

It would be cool to know what you mean by broken. Is the cursor lock just gone or what? Also, a "lock" is to a point, a "constraint" is to a region. Let's use the correct terminology to understand this fiasco better.

[ardishko]

Constraint is the right word here in that case. Here is a video with footage of what I mean:

https://storage.cloudconvert.com/tasks/486dba08-25bb-4695-a286-ab41b039ccac/2023-05-27%2023-56-06.mp4?AWSAccessKeyId=cloudconvert-production&Expires=1685308861&Signature=jpl6NHtrRBjbzXv%2FpGB0aj1gM0Y%3D&response-content-disposition=inline%3B%20filename%3D%222023-05-27%2023-56-06.mp4%22&response-content-type=video%2Fmp4

Basically, the mouse itself still moves in the background no matter of if it looks like it's constraining me to a certain region like in the video. The camera teleporting around is also another thing to note, I failed to mention it.

Long story short, the mouse does not lock and moves in the background and hits the edge of the screen which ends up looking like it's constraining me to a certain region while in reality, the cursor is just hitting the edge of the screen.

Excuse me If I sound like I don't know what I'm talking about in the video, it's because it's very hard to try to make sense of what's happening on the screen. Perhaps showing it in a screenshare would be best?

[vaxerski]

jesus christ your voice jumpscared me. Oddity oddity, I might look into the constraints code tomorrow, does sway have the same issue?

[ardishko]

Haha sorry about the voice. My mic is a little weird.

About Sway, no it did not. I will be testing it more on Sway to be even more sure but I have been using Sway for almost the whole day and left the game on to test if it would do the same thing, but it did not on multiple occasions.

EDIT: Sway has the cursor moving, but it does not hit the corners of the screen or constrain me in any way.

I play both of the test games (DRG and OW2) - Deep Rock can be played without proton (but no issues when ran with proton either), and Overwatch 2 still runs almost flawlessly for me, aside from terrible performance.

[ardishko]

No, DRG doesn't have a native linux version. The "force specific proton version" setting not being on will result in the latest stable proton version being used. (which at the time of writing is 8.0-2) Which is known to work for DRG

As for Overwatch, I have done quite a few tests on Windows and Linux, the performance seems to be relatively the same with a few drops on Wine (tested on Sway and Hyprland seperately) so the performance doesn't seem related to the Hyprland at all.

I have been trying to reproduce this in a native game like TF2 and have not been able to reproduce the issue, albeit because I keep getting kicked because I am idle. More testing is required on that. As per your suggestion (I assume you're raf#0002) I will also test this with only 1 monitor connected soon.

Since this might be relevant, here is my monitor setup data
2K 144hz (Connected via display port) +1080p 60hz (Connected via HDMI) to an AMD Radeon RX 6900XT

[ardishko]

Okay, I have tried without my other monitor (the 1080p 60hz one) and the same behavior is present (tested with DRG once again)

And also tried TF2 (native) and left it on for a while and that seems unaffected. I suspect there's a function being called via Proton that's acting weird on Hyprland but not other WMs.

[RadiantZen]

I am experiencing the same issue.

Hardware info:
2 Monitor Setup (Second monitor is disabled during testing)
GPU: AMD RX 6700 XT
Hyprland config: I can provide my Hyprland config file if needed but it is basically the auto-generated one + vim keybings and i disabled preserve_split (dwindle).

Unlike @ardishco-the-great my cursor lock doesn't work even without window switching. I can confirm sway does not have this issue. Even with setting mousewarp to "force" in wine (with regedit) the issue is still present.

Games tested:

• CSGO (Steam): Linux Native => no issue
• SWAT 4 Gold Edition (GOG): Tested on Wine => issue present
• Fallout New Vegas (GOG): Tested on Wine => issue present
• Bioshock 1 (GOG): Tested on Wine => issue present
• Bioshock 2 (GOG): Tested on Wine => issue present
• Borderlands 2 (Steam): Tested on Proton => issue present

@NotAShelf looking at your config file repo it seems you enable gamemode and disable several animations - perhaps this fixes the cursor capturing. Could you perhaps test if running your games without gamemode enabled produces the bug.

@vaxerski Did you manage to find anything?

[EvilBoi123]

Hello guys, and future people i found a workaround for this issue, not comfortable but it do makes gaming less painful.

@EvilBoi123 thanks for the tip but it does not work on single display setups, nor does it seem to fix the issue of the mouse getting stuck on the screen border when it is supposed to warp (ex. during a first-person game) on dual display.

Happy that you managed to fix it for your workflow though. Maybe instead of enabling the setting by default you could bind it to a toggle hotkey (P.S. IDK if you can change monitor settings on the fly, but it may be worth looking into).

Can confirm that you can change monitor settings on the fly. Street Fighter 6 acts weird for me in fights due to it the FPS being locked to 120, I have scripts that change my refresh from 165 to 120 and back again.

hyprctl keyword monitor DP-1,2560x1440@120,0x0,1
hyprctl keyword monitor DP-1,2560x1440@165,0x0,1

On another note, I ran into the same issue of my cursor travelling when it should be "locked" in Minecraft. As an example, when I close my inventory I expect that when I open my inventory back up my cursor should be centred. This doesn't happen, and the cursor appears to be where ever it would be had it been free to move while I was controlling the player's view. This also happens when I open the menu with escape.

This issue appears both when using xwayland to run Minecraft and glfw-wayland, and the cursor is not limited to the game window when it is "locked" and moving. This can result in some very annoying behaviour, when you open your inventory the window can defocus due to your mouse moving.
Upon the cursor exiting the window, you then need to move it BACK into the window and toggle your inventory again, and Minecraft will re-grab the cursor for controlling the player's view.

Minecraft reproduces this bug very reliably, as in, every time you open the inventory.

Can't repro.

What if you remove glfw-wayland and use regular glfw? IIRC mc uses glfw no?
