[SOLVED]patches of wallpaper showing up randomly.

parsody · 2022-08-09 08:38:16

example video - http://0x0.st/o2X6.mp4 video is broken in browser for some reason please download and play in your media player
it happens more often while zooming in/out but happens randomly too

xorg log http://0x0.st/o2XI.0.log

stderr and stdout i generated using this guide https://wiki.archlinux.org/title/Xorg#S … edirection:
http://0x0.st/o2Xl.log

lspci output http://0x0.st/o2XY.txt

currently using dwm but this used to happen while i was on i3 too. im using xwallpaper to set wallpaper but i don't think that's the problem bc i have a background in lichess.org site patches of which show up randomly while playing chess too.

i don't have xf86-video-intel installed. i have nvidia dgpu but i have blacklisted nouveau and didn't install proprietary drivers hope it can't be the culprit?

There's no nvidia GPU to begin with.
Do you use a compositor (picom)?

Try (in this order)
https://wiki.archlinux.org/title/Intel_ … RI3_issues
https://wiki.archlinux.org/title/Intel_ … flickering
https://wiki.archlinux.org/title/Intel_ … nable_fbc) (explicitly DISABLE that)

i stopped picom and it fixed it. i really want to use picom tho for transparency and stuff is there no workaround?
i do have nvidia gpu it's not showing up bc i disabled it using this guide https://old.reddit.com/r/archlinux/comm … ly_did_it/

Post your picom config and look at the second link I posted.

sorry im in the middle of something, can't reboot rn i will surely try the second link tomorrow
i run picom with --experimental-backends flag btw, running without that doesn't fix it.

Do you get the same artifacts w/ the xrender backend? (nb. that you've the setting multiple times in the picom config, maybe clean it up first)

i have now cleaned up picom conf and nothing is repeating http://0x0.st/o2Aa.txt (removed comments for readability)
switching glx and xrender doesn't work. i915.enable_psr=0 kernel parameter didn't help either.
output of sudo dmesg | grep "Command line"

[    0.000000] Command line: root=UUID=99ba3000-47e2-46c6-9acc-f7fbf3ebd65c rw noatime i915.enable_psr=0 initrd=\intel-ucode.img initrd=\initramfs-linux.img

i don't have xf86-video-intel installed so im assuming the first link is not for me?

just to be clear for the third link-

/etc/modprobe.d/i915.conf

options i915 enable_fbc=0

and no kernel parameters need to be added right?
EDIT: this didn't work either

If you've added the i915 module to the initramfs you need to also rebuild the initramfs or use the kernel commandline (it's generally the more transient and robust approach), add "i915.enable_fbc=0" along "i915.enable_psr=0"
As for DRI3,

The wiki wrote:

For the modesetting driver, this method of disabling DRI3 does not work. Instead, one can set the environment variable LIBGL_DRI3_DISABLE=1.

However, because of

switching glx and xrender doesn't work.

Is this exclusive to the browser? If so, does it happen if you start "firefox -safe-mode"?

i rebuilt initramfs and rebooted, same result
strangely it doesn't happen in firefox --safe-mode but refreshing firefox doesn't work, i also tried deleting ~/.mozilla & ~/.cache/mozilla and reinstalled it still doesn't work.

What does that mean?

Probabl not.
https://support.mozilla.org/en-US/kb/pe … e-settings - disable "Use hardware acceleration when available" and see whether regular browser instances are still affected.
If not, exporting LIBGL_DRI3_DISABLE=1 (at least to FF) stands a decent chance to fix this.

unchecking hardware acceleration worked thank you so much!!

killall firefox; LIBGL_DRI3_DISABLE=1 firefox

might work w/ hw acceleration enabled, if you prefer.
