Is anyone else here running VRR-patched Gnome with an AMD GPU? I think I might be narrowing in on a bug but it would be nice if someone else could test and verify, too

FFrozen Single GPU and dual GPU passthrough are *very* different beasts. I researched si...

HikariKnight•2/27/24, 3:01 PM

i do both single and dual gpu, i also develop 2 tools to specifically help with gpu passthrough (mainly dual but one of the tools is useful for both)

testers are few and far between (especially since i dont use the main tool myself anymore since most my stuff is now ostree based)

TaylerOP•2/27/24, 3:05 PM

And to clarify a bit more, I think VRR does not function properly when running games with high GPU utilization unless you disable KMS modifiers by setting MUTTER_DEBUG_SEND_KMS_MODIFIERS=0

TaylerOP•2/27/24, 3:05 PM

I believe in both Xorg and Wayland but most noticably in Wayland.

Varian-Killbot•2/27/24, 3:08 PM

Unfortunately, removing the args was definitely not the fix, but I expected that anyway. Regardless, good to remove args I won't actually be using lol

TaylerOP•2/27/24, 3:11 PM

I've been trying to figure out what's going on with VRR on Wayland for a while now and the other day I finally put together this theory from several different issue tickets in different window managers. Many of these WMs and DEs just use VRRTest or something to test that VRR works, but the issue only pops up when you're running an actual game. If you start up VRRTest, then start a demanding game on another workspace and switch back to VRRTest, you should see that VRRTest starts to stutter and skip. When I disabled KMS Modifiers, VRRTest no longer stuttered and skipped--it's also noticable in game of course, but checking VRRTest with high GPU load is a more consistent and obvious way to see if VRR is still working.

TaylerOP•2/27/24, 3:11 PM

I'm not really sure where to put this information--since it's happening in every WM I've tried, I think it's probably an AMD bug? But if disabling modifiers fixes it, then it's also something that WM/DEs could work around, so...

TaylerOP•2/27/24, 3:14 PM

And also something bazzite could work around, if it's found this really is affecting other AMD users

Jan•2/27/24, 3:16 PM

so what you are saying is that the GPU can't keep up the frametime and so starts stuttering when expected to spew out as many frames as possible

Jan•2/27/24, 3:17 PM

I dont think this is a bug unless you can verify this on games that aren't very demanding

TaylerOP•2/27/24, 3:25 PM

It appears to be a frametime issue, yeah. But the point of VRR is that your frames are synced to the refresh rate, which is only useful when you're playing a demanding game that can't hit your max refresh rate, right? So if VRR "works" for low GPU usage situations but not high GPU usage ones... isn't it pretty much not working?

TaylerOP•2/27/24, 3:26 PM

I did find a ticket from I think a year ago, I can find it in a sec, where previously Gnome disabled modifiers on AMD because of some issue with xwayland. This wasn't VRR related but it at least shows there's a history of this being an issue for functionality I guess

TaylerOP•2/27/24, 3:29 PM

This is the revert for that, looks like modifiers were preventing direct scanout for DRI3 clients in xwayland: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3030

TaylerOP•2/27/24, 3:34 PM

Also seems this was an issue people found 3 years ago: https://gitlab.freedesktop.org/mesa/mesa/-/issues/4308

TaylerOP•2/27/24, 3:38 PM

Lots of discussion in this issue as well on sway, some of the testing people did in here seems to indicate disabling direct scanout can fix it as well: https://github.com/swaywm/sway/issues/5601

Virulent•2/27/24, 3:47 PM

Did you change the power profile to 3d_fullscreen?

Virulent•2/27/24, 3:47 PM

Because that's a known issue with AMD and has been for like two years

Virulent•2/27/24, 3:47 PM

You need to change the power profile to 3d_fullscreen

TaylerOP•2/27/24, 3:47 PM

Yes, I've had that fix in place for a long time

TaylerOP•2/27/24, 3:48 PM

For a long time I didn't think the issue was with VRR itself so I was running down other known issues like that power profile one

Virulent•2/27/24, 3:48 PM

Ah so it is a gnome-vrr bug?

TaylerOP•2/27/24, 3:49 PM

That's what I'm not sure about. It could be? But it seems there's similar issues in sway and hyprland

TaylerOP•2/27/24, 3:50 PM

and also I'm not completely confident that it's a generalized issue for everyone with amd on wayland, that's what I'm trying to figure out. it could be some specific setting or something

Virulent•2/27/24, 3:50 PM

I can try it out on plasma

not a folder, just a file

should also be various .gamescope ones

It looks like it might be upset because I disabled the Deck BIOS checks? Because I'm not running on a Deck?

Kyle Gospo•2/27/24, 5:43 PM

might be related, but others are experiencing this without that

This is very helpful, looks like it's not properly returning the "no update" code to steam

Updates do seem to work without issue from desktop mode via topgrade

Zelda•2/27/24, 5:55 PM

hey, it's me again. i tried reinstalling everything and doing everything mostly by the book (also tried using one esp) but my bazzite install still goes in emergency mode. I also tried not creating a root account since it was advised against in the guide but that didn't help either... i'm at a bit of a loss :(
