Steps to reproduce:

open https://www.nasa.gov/specials/trackartemis/

Actual results:

half of the screen is painted bright magenta, also while the page is loaded screen is painted magenta for a while. No such issues in chromium - check the attached screenshots

Expected results:

page should've been not painted magenta

firefox 107.0/linux

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

Hi, thanks for reporting this.
Looks like this is hardware/driver specific, I can't reproduce the issue on my computers. Please paste the content of the graphics section of your about:config page here, it has useful information that could help with investigating the issue.

ni? Kelsey since this is WebGL related.

If by 'graphics section' you mean gfx.*, here goes. Note that I have another graphics issue: for some reason I cannot enable hardware graphics acceleration, after setting media.ffmpeg.vaapi.enabled to true it responds by setting gfx.blacklist.vaapi to 4 and gfx.blacklist.vaapi.failureid to FEATURE_FAILURE_VAAPI_TEST_FAILED and decodes video using CPU only. But then it should be less affected by drivers and such, shouldn't it?
Nvidia GeForce GT 1030 supporting VDPAU feature set H - good for anything up to 8-bit H.265, Nvidia video drivers 470.129.06, VDPAU and VAAPI are installed; chromium, vlc and mpv have no issues with hardware video acceleration on this system, only Firefox for some reason cannot use it.

My answer in the previous comment somehow blended with the quote, sorry about that

Sorry, the Graphics section of about:support, please!

Attached. I've upgraded nvidia graphics drivers, but it changed nothing, and hardware acceleration still doesn't work.
