Laptop camera started being laggy

I've a Dell XPs13 (9300) laptop with an inbuilt camera.
All was running fine for years, though the camera picture has just started to be very laggy.
I've tried multiple browsers (FF, Chrome) and used webcamoid, and all have the same laggy effect.

Any tips gratefully received.

Re: Laptop camera started being laggy

Can you tie the lag to a certain update or change you did recently?

Also did you try a reboot?

I've tried multiple reboots
I cant pinpoint a specific update, I just recently noticed it!

Re: Laptop camera started being laggy

Is the issue also present on the linux-lts package? Which kernel package are you using at the moment?

If you want you can also check if its a problem with the future version of the kernel:

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.10rc7-1-x86_64.pkg.tar.zst

Kernal: 6.9.8-arch1-1
Tried future version, but /boot ran out of space....

Re: Laptop camera started being laggy

Maybe you can disable fallback initramfs generation as advised in the Wiki below?

Change PRESETS=('default' 'fallback') line to PRESETS=('default') in all .preset files in /etc/mkinitcpio.d/.

(snippet taken from https://wiki.archlinux.org/title/Mkinit … dule_XXXX)

Did you have a chance to test the lts version?  If you still have that one maybe you can uninstall it temporarily

Also how big is your boot partition?

I disabled fallback and managed to try "6.10.0-rc7-1-mainline" and the issue is still there!
Boot partition is 200mb...

Re: Laptop camera started being laggy

Alright, thats interesting What about the lts version? Maybe swap out the mainline install for the lts version
You could also try an older "linux" package, i.e. 6.8 from the archive: https://archive.archlinux.org/packages/ … kg.tar.zst
