PrusaSlicer 2.9.0 Linux flatpak displays blank Plater screen

[tsmaster]

I've been using PrusaSlicer on Linux for several versions, and have been using the new "flatpak" 2.9.0 build for most of January. Today, I tried running it, and got a blank main view (see image above). I went back to 2.8.1, which still works fine.

In between the last time that 2.9.0 ran correctly and now, I believe I upgraded my nVidia CUDA software (auto update) and rebooted.

I tried running PrusaSlicer 2.9.0 with --opengl-debug, but that didn't add any information, any helpful error messages to the console output. I do see a bunch of this message:

18:59:18: Debug: window wxTreeCtrl@0x577b6af5f100 ("treeCtrl") lost focus even though it didn't have it

but I've seen that before, and it seems harmless (if weird).

Hello, @tsmaster , A similar issue was addressed here #13653 (comment), that this could be an error related to the graphics driver. Could you check, please? Thank you, have a nice day
