Hard to say, maybe it helps to avoid some net play issues. Fixed in ac47166.

So, should this be removed? What was the point anyway?

The glitch is caused by cl_waitforsave CVAR. Set it to true and the problem will gone.

I always make backup copies for such cases.

My configs:

I've always updated GZDoom simply by replacing all files in the root folder with new files from the archive. Ini-files, as far as I remember, were created even at versions 1.8.? and were not created anew.

That's bad. You should rename or move config file instead of deleting it.
If you managed to reproduce the problem again, post you .ini file.

Thanks, it works. Yes, I deleted all ini-files and it stopped. Now i have to reconfigure everything anew ...

Works fine for me playing vanilla Doom II with GZDoom 3.2.5 on Windows and macOS.
Did you try without any mods and (optionally) without .ini file? A video showing this bug could help too.

I probably chose the section incorrectly, because this problem appears both in Software and in OpenGL, but it looks different ...

I ran into a very annoying problem when I updated GZDoom to version 3.2.5. The bottom line is that if you save a game (or load a saved one) during a demo (a recordmap), the image on the screen becomes unstable. A map can be any. The picture fades, is interrupted by a black flicker of the screen, sometimes only the sky texture is displayed, without geometry of the level. However, judging by the sounds, the gameplay does not stop. This also does not result in GZDoom crashes or any error messages.

What is described above is true for OpenGL. In the Software, when you try to save in demo, the picture does not disappear and does not flicker, but it stops updating, as if the player is standing still, and the sprites of the weapon disappear. The picture is rarely updated only when you rotate the camera. In a normal game, without recording a demo, such manifestations do not arise.

I had to return to version 3.2.0 on which I was before. I can not know if there is a similar bug in intermediate versions or it appeared only in 3.2.5. I also assume that the problem may be in my old drivers (my PC is not new). I ran tests on the notebook, and got the identical result. Again, in version 3.2.0 everything is fine.

I ask you to conduct an experiment with recording the demo yourself. If this is a problem on my side, please explain what I'm doing wrong.
Thank you in advance.
