No GUI, Error on startup

[Raketenphysik]

I get this if I try to launch after a fresh installation via Flatpak:

(process:2): Gtk-WARNING **: 07:32:20.929: Locale not supported by C library. Using the fallback 'C' locale. MESA: error: Failed to query drm device. libEGL warning: egl: failed to create dri2 screen

This is on OpenSuse Tumbleweed, KDE desktop running X11. Let me know if I can help out with any further information.

Hello!
Have you tested it on a wayland session before?

[BuddySirJava]

@Raketenphysik I tried with Arch X11 KDE, Kubuntu X11, and Debian X11 KDE, but I couldn’t reproduce the same crash you encountered. Yes I could get the same errors but not the crash.
Still, I’ll add a fallback method to proceed with software rendering for better compatibility.

Could you please test the Flathub release on Wayland?”

[Raketenphysik]

I can confirm that switching to Wayland it starts without crashing! Let me know if I can investigate any further. Regards!

[BuddySirJava]

I added a fallback method for X11 just in case.
Also I could simulate the same crash on myself by maximizing or full screening the app.
I can confirm that this crash has been fixed for myself. See if you could redo the crash on latest git build.

I will update Flathub version soon

I am now on version 1.3.0 - I understand that this is the updates version. Unfortunately the problem still persist. Let me know if you need any further input. Rgrds!

I just fired up Tumbleweed as a VM using VirtualBox on the same machine. This runs without issues. This is a bit funny. The host is more or less a plain vanilla Tumbleweed without any fancy tweaks. I am using quite a lot of different software without any issues so far.

I sorted this out by adding "Direct graphic rendering" under "Device Access" editing the Flatpak permissions via Discover. After adding this permission everything runs fine.

Oh.... I need to consider that, you are right.
Thank you for digging into the problem
