Yes, that's exactly what my problem was. I installed an older version to get around what I had assumed was an OpenGL issue. It worked, and oddly enough, all the new features showed up too. I guess I've got a hodgepodge of software chunks on this PC now. Which means at some point, something will break and I'll have to spend a few days either archiving data files and starting over, or hand-picking the bad parts of different applications out.

I went with 2.8.0.

Unfortunately the given argument did not work for me... Any idea what kind of debug information to look for? I could not make sense out of the following debug info:

flatpak run com.prusa3d.PrusaSlicer --opengl-compatibility

Don't know if it is the same problem, but I was getting something similar on my RPi500 with the flatpack install. Seems Raspian doesn't have the required OpenGL version. But launching with the following gets it to work on my RPi500:

flatpak run --env=MESA_GL_VERSION_OVERRIDE=3.2 com.prusa3d.PrusaSlicer

Maybe that'll work on your systems?

I can't pretend to understand how this works, I found this method after a bunch of googling.

I got the same problem on Fedora 42 if you mean this:

PrusaSlicer 2.9.2 not showing the main window

Without updating anything on my computer (Ubuntu 20.4) PrusaSlicer 2.9.2 now has nothing but a white window on the Plater tab. All other tabs work great.
Is this some new feature Prusa is providing me? I can still add STL files, but I can't slice, because there's no dimensions.

Do I need to try the Online version I got an email about a couple days ago?
