      I was using 20.04LTS and up until 4.8 the emulators were working fine.
      Now, for some reason, the emulators are all stuttering - in particular picodrive and lr-mame2016. I was using an intel NUC with a 5th Gen i5, and it worked fine on that until now.

      Even after upgrading to the 22.04LTS beta, and replacing the NUC with a gen 11 i5, I'm still getting stutter. I tried recompiling the emulators again, but the stuttering persists
      I also have an ubuntu 20.04LTS system on AMD Ryzen 5700G, but no issues there.

      I think it must be display driver related. I have tried Ubuntu in both wayland and x.org modes, but neither work.

      Note that that I was routinely upgrading 4.7 over time to 4.8
      I wonder if completely doing a fresh install of Retropie would fix it, and if so, how would I completely wipe it out (including all it's prebuilt drivers) to fix this - short of reinstalling the OS?

      It is also a bit frustrating that I cannot force a recompilation of every installed package, as updating only does this for emulators that have no updates.

        Does this happen only with RetroArch's libretro cores or does it happen also with standalone emulators ?
        Can you get a verbose log from running a game and post it on pastebin.com ?

          Everything seems affected. I tried opening vice (non lr) and that had the same issues.

          See pastebin below. I ran outrun (bootleg) in lr-mame2016 for this test.
          I note that it's complaining about not having enough frames to run with, but I don't understand as to why that's happening.

            It says so in the message (Requires to run for at least 4096 frames.). Because you only run the game for 30 sec, it doesn't have enough frames to estimate. But that's just a symptom of the issue.

            I see that Wayland session is detected - are you using the default desktop env (Gnome) with Ubuntu ?

              Yep. Standard gnome ubuntu. Tried it with both wayland and X sessions.
              Same problem though. Stutter won't go away.
              Note that the stutter also affects sound. It's not a simple TV mode that's causing tearing. My TV is using Game mode.
