Apologies for the rather anemic bug report -- I don't know if "stuttering" is even the best way to describe this behavior -- I just don't know what kind of diagnostics this would warrant.
I've been able to reproduce this on GZDoom 3.7.2, 4.1.3, and g4.2pre-324-g43041c21d-m. The issue is that the game freezes up every other second. This is most noticeable in the menu if I hold down one of the arrow keys, which I've attempted to record:
Keep in mind that even when using the software renderer the final result is still presented by OpenGL in GZDoom.
I just tried launching GZDoom here and I don't see any stuttering at all. That's on a Windows system though. Last time I tried GZDoom on Linux is ran quite terribly. It had a very high frame rate yet at the same time it didn't feel remotely smooth. At the time I figured it was probably my Linux distro or the nvidia driver acting up.

If only someone experienced on linux would go ahead and make an equivalent version of polybackend for SDL2, it should be pretty easy.

You only have to implement 4 functions or so to support that branch on Linux. Nevertheless, it doesn't explain why OpenGL ran so poorly on my Linux machine last I tried it. I would have examined it closer if it was my primary platform for development, but I didn't have any clear indicator of what the problem was for me to fix it using joe.

Sadly, no.

My apologies, I just tried running EDuke32 and ioquake3 and found that they have the same issue. I thought the problem would lie in GZDoom as other games were working fine just a few days ago, but that's not the case any longer. I'll mark this as solved, since it's apparent that this is not GZDoom-related.
