Hey, thanks for the report — sorry its giving you a white screen.

Thats almost always a WebKitGTK rendering issue on Linux (Tauri uses the systems webkit2gtk under the hood). A few things would help me narrow it down:

1. What distro + version are you on (Ubuntu 22.04, Fedora 40, Arch, etc.)?
2. X11 or Wayland session?
3. GPU / driver — especially if its NVIDIA proprietary, thats usually the culprit.
4. Can you run the AppImage from a terminal and paste whatever it prints?

   ./Focuser_0.1.8_amd64.AppImage
   

5. As a quick test, can you try launching it with these env vars and see if the UI actually shows up?

   WEBKIT_DISABLE_DMABUF_RENDERER=1 WEBKIT_DISABLE_COMPOSITING_MODE=1 ./Focuser_0.1.8_amd64.AppImage
   

   If that fixes it, Ill bake those into a launcher script inside the AppImage for the next release.

Also make sure webkit2gtk-4.1 (or 4.0 on older distros) is installed — on Ubuntu/Debian thats sudo apt install libwebkit2gtk-4.1-0.

Re: JS vs TS — fair question. I started this with a friend and he scaffolded the frontend in plain JS, and honestly the UI surface is small enough that I never felt enough pain to justify migrating the whole thing. Its on the list, just not high priority while Im still nailing down the core blocking behavior. Happy to take a TS migration PR if youre interested though.

./Focuser_0.1.8_amd64.AppImage

Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...

It's a Tauri issue.

Hi I will check the issue that you are having on Linux.

For the other questions it's just my side project I love developing so I don't have a proper roadmap.

For the performance I tested it for Windows it have negligible impact on performance and it takes a max of 15 MB of ram while running in background.

You can use the blocking mechanism and optimize the performance based on these apps

MacOS: SelfControl
- Unable to access those websites even if you restart your computer or delete the application.

Linux: Timekpr-next
- Timekpr-nExT relies heavily on DBUS for system interaction:
- Uses DBUS interfaces provided by the system.
- Exposes its own DBUS interfaces.
- Can integrate with any client application or control panel that supports DBUS.
- Timekpr-nExT connects to these DBUS objects once, caches them, and mainly calls them during execution for efficiency

Arch Linux wiki: Parental control

Gnome 50 also added parental control
"Under the hood, the foundations for web filtering support has also been added — a backend service that can enforce content filters for child accounts once the user interface is completed in future updates, allowing age‑appropriate web restrictions without breaking web security or relying on curated lists."

Gnome: Parental controls screen time limits backend

Can you support other Linux distros like Arch Linux, Fedora, etc.
App image is unusable because of that bug
And it's too easy to delete an app image
