screen artifacts in gamescope-session on the V3

An odd screen artifact is showing up for me on my Minisforum V3 after updating to the latest bazzite. It only affects gamescope-session, it disappears on desktop mode.

I think I've seen some ROG Ally X users report a similar issue previously, so perhaps it's related to VRR screens.

I updated from 07/23 to 07/28

edit: workarounds below, any of these should work:

suspend-resume cycle makes it go away
restart steam client also makes it go away
reboot device
rollback to 07/22 OS version

I'll check the 07/26 and 07/25 images to see if the issues are there too

@Kyle Gospo I’m going to spin up a vanilla Gamescope rpm on copr for testing situations like this, with the amount of patches we have it’s going to get hard to narrow down upstream issues or patch issues.

matt_schwartz•7/30/24, 12:27 AM

or other issues entirely

matt_schwartz•7/30/24, 12:27 AM

also it looks similar to that dude with the Ally x who thought it was a hardware thing

AruOP•7/30/24, 12:30 AM

present on 07/26

AruOP•7/30/24, 12:30 AM

for to replicate the bug, you need to go back and forth between desktop + gamescope-session at least once

AruOP•7/30/24, 12:49 AM

ok, not present on 07/23

AruOP•7/30/24, 12:49 AM

accidentally skipped 07/25, let me check it now

AruOP•7/30/24, 1:02 AM

@Kyle Gospo confirmed 07/25 introduced the bug

AruOP•7/30/24, 1:02 AM

so last known good image is 07/23

AAru @Kyle Gospo confirmed 07/25 introduced the bug

Kyle Gospo•7/30/24, 1:03 AM

nice, Ill revert gamescope for now

AruOP•7/30/24, 1:03 AM

I don't know if this will be the same for the Ally X

AruOP•7/30/24, 1:19 AM

for anybody who has this issue, temp workaround is for to rollback + reboot to 07/22

note that this will lock you to the 07/22 bazzite version.
If you want to resume regular OS updates in the future once bugs are fixed, run:

Oh yeah that’s the exact same thing. I finally don’t feel like the only person to have seen a UFO anymore!!

is that on the version aru said to rebase to until gamescope is reverted

HHikariKnight is that on the version aru said to rebase to until gamescope is reverted

PubisDeciusMons•7/30/24, 2:04 AM

How do i see the version?

PPubisDeciusMons How do i see the version?

HikariKnight•7/30/24, 2:05 AM

you can use the commands aru mentioned to easily rebase to older versions and back to stable once the problem is fixed

PubisDeciusMons•7/30/24, 2:11 AM

Yep i can confirm I have the 7/28 version

PPubisDeciusMons Yep i can confirm I have the 7/28 version

HikariKnight•7/30/24, 2:11 AM

rebase to 7/23

HikariKnight•7/30/24, 2:12 AM

it will lock you to 7/23 until you rebase back to stable

HHikariKnight rebase to 7/23 `bazzite-rollback-helper rebase 40-stable-20240723`

PubisDeciusMons•7/30/24, 2:12 AM

OK and that command locks it so it won't auto update to 7/28

HikariKnight•7/30/24, 2:12 AM

yep

HikariKnight•7/30/24, 2:12 AM

aru confirmed that version isnt affected

HikariKnight•7/30/24, 2:13 AM

aru is testing reverting gamescope atm i believe so next stable release might have it solved

PubisDeciusMons•7/30/24, 2:13 AM

ok just reboot is ok or does it need hard power off/turn back on

PubisDeciusMons•7/30/24, 2:22 AM

Got it, rebooted and hopefully all good! Thanks you guys are absolutely top notch!

AruOP•7/30/24, 2:23 AM

could you swap between game mode and desktop mode a few times, and see if the bug pops up or not?

PubisDeciusMons•7/30/24, 2:23 AM

sure

PubisDeciusMons•7/30/24, 2:24 AM

just to be clear when i was experiencing that bug, it would come and go in spurts. For example if it happened, it could be repeated consistently multiple times. Then hours later or the next day, i could switch back and forth without the bug occurring, only for it to pop again. so it was always intermittent.

AruOP•7/30/24, 2:24 AM

for me it always pops up after swapping between desktop and game mode at least once

AruOP•7/30/24, 2:24 AM

i was wondering if it was the same on the Ally X

PubisDeciusMons•7/30/24, 2:30 AM

Ok, so switched it 2x and the problem did not recur. However everything is running a bit sluggishly as it re-verifies the steam installation and stuff - i assume that is normal for awhile after rolling back.

AruOP•7/30/24, 2:31 AM

aight, let us know if you run into the problem again, or other problems.

AAru aight, let us know if you run into the problem again, or other problems.

PubisDeciusMons•7/30/24, 2:31 AM

Will do. This was the single most noticeable/scariest issue, everything I've had feels like the garden variety minor bug that gets fixed in future updates type.

AAru aight, let us know if you run into the problem again, or other problems.

PubisDeciusMons•7/30/24, 2:43 AM

Have you noticed that gaming mode is running extremely slowly after roll-back? like i just fired up Baldurs Gate 3 and it's taken 10 minutes and it still hasn't finished "processing Vulkan shaders". When I ran it the first time it took less than 2 min to finish the initial load/startup process before going into the game.

AruOP•7/30/24, 2:44 AM

you can generally skip vulkan shader processing nowadays

AruOP•7/30/24, 2:44 AM

there's been improvements in the kernel for AMD GPUs that basically makes the shader processing optional for most games

PubisDeciusMons•7/30/24, 2:45 AM

are you noticing long load times for everything though? if gaming mode is this slow throughout i might just go back to 7/28 and live in Gaming mode without switching to desktop until a new stable version comes out that fixes the gamescope bug.

AruOP•7/30/24, 2:47 AM

let me try real quick, gimme a few mins

AruOP•7/30/24, 2:57 AM

ok, so it took me a bunch of tries, but artifacting popped up for me on 07/23

AruOP•7/30/24, 2:57 AM

which means the bug was introduced earlier

PubisDeciusMons•7/30/24, 2:58 AM

Argh

PubisDeciusMons•7/30/24, 2:58 AM

Looks like the slow performance issue is resolved by rebooting a 2nd time after the inital reboot into 7/23

PubisDeciusMons•7/30/24, 3:00 AM

I'm guessing that it's best to just leave my Ally X in 7/23, live in gaming mode, until the bug is fixed. Sounds like you guys are not far along from fixing it anyway.

PPubisDeciusMons I'm guessing that it's best to just leave my Ally X in 7/23, live in gaming mode...

AruOP•7/30/24, 3:00 AM

that'd be the easiest for you, yeah

AruOP•7/30/24, 3:01 AM

and tbh, there is the off chance that the bug I'm encountering is different from yours
