Extra Info:

The logs don't show this but opening the appimage through the terminal I also get this error:
'Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...'
It shows up here:

INFO] Cortex server spawned successfully. PID: 3713026

When I submitted issue #5284 I was running version 0.5.17 and the app opened and rendered properly. (This might be related to an update between those versions).
When I did try the beta version of the app and the same thing happened. I waited on opening an issue since the app I tested was in beta.

I'm also having this issue with Fedora 42 GNOME. This occurs on stable version 0.6.3, and beta version 5.18-rc6.

There are some existing issues on GitHub relating to EGL_BAD_PARAMETER:

• Could not create default EGL display: EGL_BAD_PARAMETER. Aborting... gitbutlerapp/gitbutler#5282
• Linux: window does not display properly (bad EGL parameter) spieglt/FlyingCarpet#104
• Could not create default EGL display: EGL_BAD_PARAMETER. Aborting... gitbutlerapp/gitbutler#5282

My app.log and cortex.log files are in this gist: https://gist.github.com/maxrr/ed8b0f5bcdb2bbf52877afb59df568c3

[ibixina]

same issue with fedora 42. it is happening from version 0.6 onwards

[antonio-RN]

Same issue in Aurora distro (Fedora atomic), console shows Could not create default EGL display: EGL_BAD_PARAMETER. Aborting... and app doesn't render. Tried 0.6.3 and 0.6.4 AppImage.

[0rzech]

It looks like it has been fixed in #5463 and is awaiting 0.6.5 release. 🎉

[0rzech]

I have tested 0.6.5 and it does render on my computer. 🎉

[Theblackcat98]

I have also tested version 0.6.5 and can confirm that it does render!
