Using color picker in GIMP sets focus to main window

[hirschsystems]

Hyprland 0.51.1
When interacting with color pickers in GIMP the mouse focus gets jostled back to the main window and the two fight for focus.

stayfocused on the color picker window does not alleviate the issue, not sure what other rules would be applicable.

I don't really view this as a fix more like a "this is completely broken and I need to use it so this at least lets me use it" workaround. This was not my solution someone came up with it in discord but I forget who.

# GIMP windowrules
# Color picker goes bonkers when a file is open the below conflicting rules fixes that
windowrule = nofocus, initialClass:^(org.gimp.GIMP)$, initialTitle:^(Change .* Color)$
windowrule = stayfocused, initialClass:^(org.gimp.GIMP)$, initialTitle:^(Change .* Color)$
windowrule = noblur, initialClass:^(org.gimp.GIMP)$, initialTitle:^(Change .* Color)$
windowrule = opaque, initialClass:^(org.gimp.GIMP)$, initialTitle:^(Change .* Color)$
windowrule = suppressevent urgent, initialClass:^(org.gimp.GIMP)$, initialTitle:^(Change .* Color)$

When the next update to hyprland comes out the rule will need to be changed as the syntax is different. So just for reference here is the same set of rules for the new syntax when that's out:

# GIMP windowrules
# Color picker goes bonkers when a file is open the below conflicting rules fixes that
windowrule = no_focus 1, stay_focused 1, no_blur 1, opaque 1, suppress_event urgent, match:initial_class ^(org.gimp.GIMP)$, match:initial_title ^(Change .* Color)$

Having this issue as well. With Hyprland 0.52.2-2 and GIMP 3.0.6-2
Though unfortunately tannerellen's rules don't fix the issue for me.

I had to replace the class match (^(org.gimp.GIMP)$) with ^gimp$ but the rule works otherwise

[tannerellen]

Oh yeah, sorry. Forgot to mention I use the flatpak so that's why my rules are org.gimp.GIMP.

Can't repro on latest git.

No window rules involved.

Color picker detaches as expected, floats, and no cursor/focus probs.

Plain old hardware cursor here, no hyprcursor.

Also can't repro on the random 0.52-ish git commit I'm on and gimp 3.0.6. Don't think I have any rules that would affect this either. I have an image open.

[tekstryder]

If by document you mean an image, yes for sure.

I tested using the color picker to set and apply colors to an image.

I kinda doubt the refactor "fixed" this if you're just a few commits behind.

Me, I'm a guinea pig and was ready for explosions, so jumped right in.

All good with everything I can throw at it. I don't steam/game tho..

[tannerellen]

Looks like it's due to the misc:focus_on_activate setting in hyprland.

focus-on-activate.mp4

[Dregu]

Oh that always sounded like a nightmare to enable globally, a windowrule for the browser is just about right.

[tekstryder]

Glad you've found the culprit. I've never used that setting.

[tannerellen]

OK so after testing just to fully update this thread... Looks like this is caused by the misc:focus_on_activate setting. So either disable that setting globally and set window rules for apps you want to have it, or just disable that setting with a windowrule for the gimp:

windowrule = focus_on_activate 0, match:initial_class ^(org.gimp.GIMP)$

I'm using the gimp flatpak so if you aren't, replace org.gimp.Gimp with just gimp
