Hardware acceleration causes glitchy graphics on NVIDIA 2060

Firefox 104
Windows 10

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:104.0) Gecko/20100101 Firefox/104.0

Steps to reproduce:

  1. Turn on Hardware Acceleration from Firefox' settings
  2. (for example) go to this link and try scrolling

Actual results:


There's too much graphics glitch happening that keeps me from using the hardware acceleration.

Without the hardware acceleration, Firefox puts an enormous load onto my CPU while watching 4K-Videos etc.; which renders my computer much slower. Thus I prefer to use hardware acceleration.

Expected results:

The graphics wouldn't glitch out

OS: Unspecified → Windows 10
Hardware: Unspecified → x86_64

The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Component: Untriaged → Graphics
Product: Firefox → Core

Oh, by the way, some stuff I forgot:

Disabling the hardware acceleration lifts the issue
Chrome with Hardware Acceleration works fine

Summary: Hardware acceleration causes glitchy graphics → Hardware acceleration causes glitchy graphics on NVIDIA 2060

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.

Ever confirmed: true

Today I removed my GPU driver with DDU and reinstalled the latest version 516.94 for RTX2060 (Mobile). The issue still persists.

I also discovered that Thunderbird also has the same issue, so I had to disable hardware acceleration for it as well.

dorukgencel, is this a regression?

dorukgencel, is this a regression?

No, I have been using chrome until last 1-2 weeks. I have started using Firefox (and Thunderbird) for the first time on my hardware from Firefox 103 on.

So I've done a clean install of my Windows Instance, thinking maybe it might make a difference
(since I had time and have been using that instance 7/24 for about 2 years)

The bug still persists in Firefox & Thunderbird

Hardware Acceleration works fine in the following software: Steam, Discord, Spotify, Edge, Chrome
(to check the hardware) GPU works as expected in the following games for at least 1 hour: Fallout 4, War Thunder, Forza Horizon 5
Stress tests such as Unigine Heaven & Unigine Valley run without issues.

Can you try setting gfx.webrender.compositor=false and restarting Firefox to see if that helps?

Flags: needinfo?(dorukgencel)

It did!

I enabled [Use hardware acceleration when available] as well as [Use recommended performance settings] and set [gfx.webrender.compositor=false] in about:config; and restarted the browser

The glitches disappeared completely. I checked if Firefox is actually using GPU now with a 4k-video on Youtube, and yes it does!

I changed [gfx.webrender.compositor=false] in Thunderbird as well, which also worked.

Thank you so much

:bhood, could you have a look please?

Glenn, another one that appears to involve WR. Putting on your radar for evaluation.

Severity: -- → S3
Component: Graphics → Graphics: WebRender
Flags: needinfo?(bhood) → needinfo?(gwatson)
Priority: -- → P3

Looks to be another one of these DirectComposition + Firefox + nVidia + high refresh rate glitches we have. I think we need to get someone to reproduce this locally again and spend some more time trying to work out what causes it.

Bob, let's discuss this week who can look at it?

I don't have much experience, but let me know if I can be of any help
