[Never mind] Waveform 13.1.2 graphic glitches on Linux Mint 21.3

[havran]

Kernel: linux-lowlatency-hwe-6.5
Graphics card: AMD Radeon RX 6500 XT

Last night I installed W13 on Linux Mint and immediately had trouble (during the setup steps) with panes being blacked out, random black rectangles, and sometimes the whole screen going black temporarily.

When I realized that Linux Mint (fresh install) was using Kernel 5.15, I thought maybe a kernel upgrade would help, so I changed to the kernel mentioned at the top, which did not really result in an improvement.

Sometimes during the glitching I could not close the main app window the usual way (the X in the titlebar), and had to log out to close it. Even xkill did not work to close a glitching instance.

Any tips from the devs or from other Linux Mint users re: what might help?

I am not using Linux Mint, but an often made recommendation here on the forum is to change in
SETTINGS - Advanced - Performance - GUI Rendering Mode
from option "OpenGL Renderer" to option "Software Renderer".
However, this would not relate to the installation procedure but "only" to the later on usage.

Also, as you mention a fresh Linux install and this might by default configure graphical sessions to be based on Wayland nowadays, maybe try to base the graphical session on X11.

Please drop a note for future readers if this, or what else solves the problem.
Best wishes and good luck!

Thank you! That sounds promising. I'll give it a try in the next day or two and report back.

UPDATE: Just gave talby's suggestion a try on a fresh install of Waveform 13.1.2, and software rendering worked fine. Then I thought that to be scientific about this I should switch it back to OpenGL rendering -- however, that mode also works fine now.

So there must have been some other wrench in the works causing those video glitches last night when I installed W13 the first time. Hmm.

I do remember that during the first launch of that first install, there were competing pop-up windows (account login, download manager notice, and I think plugin scan). There was also an error when scanning Collective (VST3), which I think I might have installed (along with DAW Essentials) before that very first launch of Waveform.

Today I first cleared out my Tracktion downloads, the ~/.vst and ~/.vst3 folders, and deleted the ~/Tracktion folder (which I had created to hold the Collective and other content), before starting over with only a fresh Waveform install and nothing else.

SUMMARY: Waveform seems to be working fine now, but now I have no idea what might have been involved with the graphics glitches the first time around. Sorry about that!

I have just seen something similar(?) and I could solve it similar(?):
After having reinstalled Waveform13 the text was not drawn in the Search tab of the Browser pane when running waveform13 for the first time. Happened in all Projects/Edits which I tester, also a newly created one. All other GUI and text elsewhere worked perfectly fine. After a restart of the Waveform app the graphical glitch disappeared.
