ZDoom

Hello. I have Linux (LMDE5) and GZDoom 4.8.2
This works on the motherboard Asrock FM2A88X Extreme6+ and AMD A10 7890K and built-ni video.
Everything worked well before, but one day I received this error:
I've tried reinstalling the app, tried replacing pk3 and wad files, but I always get this error no matter what I try.

Change the value "25.0" at line 12 in the CVARINFO.TXT file to "25". Yes, it matters.

This file is not on my computer

CVARINFO.TXT is inside the mod file. Rename it to <whatever you want>.zip and extract it, then modifiy the file. After that, re-compress the file as <whatever you want>.pk3.

Okay, I did it. Now there is another error.
But this time I really can't find the file. I used the system-wide file search, including the unpacked mod.

Huh? That's in gzdoom.pk3, a critical file. Something is really wrong with your gzdoom installation. Reinstall gzdoom.

I understand about gzdoom.pk3
I tried reinstalling it twice, tried other pk3 files,
I also tried to install ZDoom, it also does not work, but in a different way.

Use the flatpak. If it still doesn't run, then LMDE 5 is broken. Also try a full system upgrade.

But it worked before, and suddenly it stopped working. Why not working? No system-wide changes was made, gzdoom just die.
And no problems with other software.
All available updates are installed when they become available.
UPD:
I reinstall linux from LMDE5 to LMDE6, and now GZDoom almost working.

Oh boy. It seems like MESA shat itself again.

Try disabling texture filtering and using OpenGLES.
