Appimage-run qt platform plugin error

Help
1

Hi, i’ve been trying to run the Tahoma2D appimage with appimage-run and nix-alien/default.nix without success. I always get the error

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Aborted (imagem do núcleo gravada)

I really don’t know what to do… The xcb plugin seems to be there but isn’t being used. Also, the program will only work properly if you run it inside the Tahoma directory.

from Tahoma2D - Download installation instructions:

DO NOT separate the Tahoma2D AppImage or the tahomastuff folder from the Tahoma2D directory

That’s nice of them but that doesn’t stop us from texting it anyway and maybe failing.

Is your X11 otherwise working? Can you start xeyes? If not do you have XAUTHORITY env set?

Yes i can start xeyes and qt xcb apps through Xwayland.

❯ printenv XAUTHORITY
/run/user/1000/.mutter-Xwaylandauth.MKUCW1

I’m not sure what happened but Tahoma2D is working fine through appimage-run now… If i find the reason why it wasn’t working or why it started to work i’ll give an update.
