Firefox crash due to nvidia explicit sync on 6.9.10-arch1-1 with Wayland

General system Kernel, boot, graphics & hardware

Since updating to 6.9.10-arch1-1kernel Firefox has been crashing due to nvidia explicit sync on Wayland.

GraphicsCriticalError: |[0][GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1@53: error 4: explicit sync is used, but no acquire point is set

This is part of the error messaging in Firefox when it crashes which is quite long. It was said to change environmental variable from MOZ_ENABLE_WAYLAND=1 to 0 but that doesn’t work and when i boot if i move the cursor on log in it causes EOS to crash.

So i went into Firefox about:config and set nvidia explicit sync to on. Now it seems to be okay but i need to use it more to know for sure. Just wondered if anyone else has run across this yet?

This is the first issue i have had in a while on nvidia with Wayland.

Looks like it’s fixed in the Arch package:

Just need to wait for it to hit the mirrors.

Looking at this i don’t see what the fix is? Must be buried somewhere. :laughing:

Edit: Showing 5 changed files with 329 additions and 4 deletions

Edit2: I’ll just keep using it for now until this fix comes in and see as I’ll change the setting back in Firefox to check.

Hopefully it works when it’s finally released.

Sorry if this is a dumb question but how or where can i see if firefox is using explicit sync? When checking with nvtop i never see my Nvidia working it’s always my AMD igpu that’s in action. So far the only package i’ve seen using nvidia is mpv player when watching a movie.

Forgot to mention I’m currently on Arch with nvidia-open-dkms drivers and fully updated just now (including firefox 128.0-2)

It’s still crashing frequently here on version 128.0-2 when playing YouTube videos.

I have rebooted the system just in case, but the problem is still here.

Edit 1: root cause seems to be in Mesa, tracked by this issue:

Edit 2: I’m launching Firefox as an X window until this is resolved:

MOZ_ENABLE_WAYLAND=0 firefox

This didn’t work for me causing the system to crash when moving the mouse. There is a new mesa driver right now & I’m installing it.

Crashing the whole system? That’s weird; do you have xorg-xwayland installed?

Setting that variable to 0 is the only way I can still use Firefox, otherwise it would crash every 2 minutes.

Of course. I’m not saying it’s totally fixed but since i set nvidia explicit sync true on Firefox it’s not crashing like it was. It never did this before the latest kernel. Firefox was also updated recently. :person_shrugging:

Edit: So what I’m finding is that it’s not really crashing but it’s when I’m at the login screen for Kde if i move the mouse it jumps to the last entry i think before it loads the login screen which is the tty screen. I have to use REISUB to reboot it. It’s got to be the latest kernel as i didn’t have this issue before. I guess i could try downgrading the kernel.

All seems good in the settings, anyway i was just wondering how it can be checked. As said i never see any action on the nvidia when being in firefox. Next computer will for sure not be nvidia shit anymore even if they decide to fully open source.

Well I’m still having problems with crashing since updating and I know there is a pile of Kde updates in there also so i went back using snapshots and it’s working fine. It could be the kernel or something else? Think I’ll update without the kernel and try.
