kde xwayland screen tearing, flashing in games (Solved)

Fullsteam · 2024-03-15 01:44:12

This was resolved a while back by the explicit sync patch to the NVIDIA driver 555 in the repository and KDE plasma explicit sync patch

I also wanted to use this opportunity to Thank @Seth for all the help you are giving on this forum and @v1del for all the work you are also doing in moderating and answering questions on this forum.
Also to the people who worked on getting explicit sync into the NVIDIA driver.
To the Wayland team and the desktop teams who got explicit sync to where it is now in the desktop and the wonderful experience it now is as well as the more secure experience and the work on the Linux desktop in general.

A heartfelt thank you to everyone above the Linux experience would not be as good without you and the hard work you do.

Hi all

I have been using wayland since plasma 6 rolled out in the extra repositry

However i have noticed some issues with the occasional screen tear while using chromium under xwayland (This is barely noticable)
When i run games however it is very noticable specifically rather significant screen tearing (looks kind of like stuttering) in a game called oxygen not included from steam and very severe tearing and the window flashing white with minecraft.
in oxygen not included case steam and the game run under x11
in multimc minecraft's case multimc the launcher runs under wayland but the minecraft instance itself runs under x11.

Sounds like this case excluding the slow text input

also i tried running the game warsow as per seth's suggestion in the thread linked above suffering no screen tearing or issues which makes it look like this is to do with xwayland because if i run x11 not under wayland it seems to function fine beyond my desktop background going black and desktop apps dissapearing.

let me know if i need to post anything else or any of the above again with filtering

Thank you for reading all this and any help offered

edit
forgot to mention if running any games through lutris enabling dgvoodoo2 (which if i understand is a directx substitute/emulation) screen tearing is reduced significantly

that does make a significant difference
i believe chrome is still suffering lag when playing videos however when playing a game through steam is when i have noticed
and minecraft when actually playing in a world the screen is flashing white
that game oxygen not included is functioning very well
also thought i would check factorio that is going between flickering black for fraction of a second and fully black for roughly a second

V1del · 2024-03-16 01:44:26

Is chrome configured to use the wayland backend? You should configure it to do so: https://wiki.archlinux.org/title/Chromi … nd_support

Fullsteam · 2024-03-16 03:20:44

Thanks V1del thats chrome sorted because it wasn't flagged to use wayland
also turns out you can just go to chrome://flags normal method to flick the ozone parameter to wayland

x-ref reg. factorio: https://bbs.archlinux.org/viewtopic.php … 0#p2157610

Fullsteam · 2024-03-17 20:54:04

Hi sorry for taking a while to get back to this

Seth could you clarify what you mean by xref reg factorio, because i'm not sure what you mean my best guess from a couple of seconds look is reverse engineering, or something like a memory or process dump.

from something i read on reddit it could take a year for the nvidia explicit sync patch to get merged into mainline?

if thats true its either stick with xorg or transition to amd if i understand?

i'll edit with those links when i get back a bit later

https://en.wikipedia.org/wiki/Cross-reference

from something i read on reddit

… srsly?
Either way, from what I can tell xorg-xwayland-explicit-sync-git doesn't fix specifically factorio for Papapuff (did you try?)
So mainline or git, facebook or reddit - it's possibly not related to the factorio issue at all (resp. factorio might have layers of issues here)

Does the game come w/ some confgi options reg. its renderer?

Fullsteam · 2024-03-18 00:44:38

I mean i'm mainly using factorio as an example here minecraft is more the hill i'm going for specifically my 1.7.10 modpack.

however in terms of factorio i only get a couple of seconds grace before the just goes black and i have to just click and pray i clicked the right thing so pretty unworkable.

in terms of minecraft the only thing i'm having issues with is the screen specifically minecraft not the whole screen flashing white and on the main menu the graphics fragmenting severly for minecraft the only solution i've found is glfw minecraft git which is the glfw library patched for minecraft.

Cheers for the clarity on cross reference : )

seth · 2024-03-18 18:09:51

There're reports about the 550xx driver causing some "black flicker" - have you tried the 545xx or 535xx driver against this?
(nb. that the dkms versions in the ALA will NOT build against the 6.8 kernel, you'd have to try along the LTS kernel)

Fullsteam · 2024-03-24 04:11:37

I'm trying the nvidia 535.54.03 dkms module however against kernel 6.6.22-1-lts its responding withg

'make' -j32 IGNORE_PREEMPT_RT_PRESENCE=1 NV_EXCLUDE_BUILD_MODULES='__EXCLUDE_MODULES' KERNEL_UNAME=6.6.22-1-lts modules....(bad exit status: 2)
Error! Bad return status for module build on kernel: 6.6.22-1-lts (x86_64)
Consult /var/lib/dkms/nvidia/535.54.03/build/make.log for more information.

as it is nvidia 545 driver does make a difference because minecraft isn't crashing on close its properly closing
i'm trying the 535.54.03-8 driver non dkms now

EDIT

tried 535.54.03-8 non dkms non lts however that didn't work

Actually just looked at factorio forums

found this post though same kind of problem actually
https://forums.factorio.com/viewtopic.php?t=74751

in steam had to add the option --force-opengl other wise it would just be a black screen

testing minecraft still have tempermental flickering

FYI
I had to switch back to nvidia 550 driver
also i am no longer running the xorg-xwayland or xorgproto git packages (yeah it was a mistake and i will reinstall still i'm not against just sticking with xorg untill may 15th)

oh also went digging and saw this
https://github.com/NVIDIA/egl-wayland/p … 2010292221

nvidia rep saying that they are targetting a may 15th release with beta driver 555 hopefully that timeline sticks with the explicit sync patch

Been a while I held off on trying driver version 555 because of it being a beta and this being my main system.
but with plasma 6.1 implementing explicit sync in the stable branch i'm wondering how stable is the nvidia driver 555 because of course explicit sync in plasma is not useful if the graphics card doesn't support it

Thanks in advance for any feedback
