I have only installed the former and the installations are conflicting.
I am using an Nvidia card with the proprietary driver and am experiencing screen tearing on Firefox, not elsewhere.
Should I switch to try to solve my issue?
Hm so then I don’t understand running CUDA vs. non-Cuda…
Will installing the latter (with CUDA) and removing the former be helpful for my FF-tearing issues?
Cudos.
Does libva-vdpau-driver provide HW acceleration in Firefox on your system?
When I tried it, it didn’t work. It’s outdated and not recommended to use.
libva-nvidia-driver does work but you’ll need to configure a lot of parameters manually.
I haven’t experienced any screen tearing though. So can’t say if switching driver would help you in that regard.
I have a failure log in about:support though, relating to vaapi:

My system was installed in May of 2023 and it seems to have been default by then.
(Nvidia driver installed by mhwd @ cli) Maybe others have the sameissue/outdated driver?
(and yeah I’m really careful changing a running system, much costumizaition looks-wise.)
iGPU has only 2 outputs, I attach 3 screens and 1 TV to my (errr, very “cheap” in 2021-2024) GPU.
Installed: libva-nvidia-driver
Thank you after several reboots the screen tearing issue seems to be gone. (Unless upon screen auto switch off, then I have to relogin to make it go).
However, the video Video Engine Utilization stays at 0% be that for Ff-yt videos >=720p or any video that I play with VLC/Smplayer up to 4K.
So maybe my GPU can’t do this at all? CPU also goes up when I play these vids.
Might want to check the codecs supported by your device vs what yt (or whatever else) is using.
In my case my AMD is just a little too old for AV1, so I keep that disabled.
This may be possible from within an account or something, but I dont have one of those.
I use enhanced-h264ify – Get this Extension for 🦊 Firefox (en-US)
For smplayer you may want to check its settings as well.
In my case I use gpu-next.
SMPlayer is at Default there. I had set Performance > | Performance | Hardware decodeding
to nvdec-copy after the above 2 posts and I did get some small percentages in nvidia-settings Video Engine Utilization then finally, however just for videos up to HD, the rest seems to be done by the CPU.
