Weird visual glitches

[questir]

Sometimes while browsing I get some weird visual issues where some letters disappear or I get random white boxes or some letters appear distorted snowy like. It started like 2 weeks ago and happens very rarely but annoying.

I have the lastest Nvidia driver version and I also tried a fresh install with Guru3d but hasnt got fixed.

Has anyone else had this problem?

One thing that may have changed is your graphics card being whitelisted for webrender or you being added to a webrender test group. See here for details https://www.ghacks.net/2019/05/20/firef ... irefox-67/ or try going to about:config and set gfx.webrender.all to false.

Did you check for hardware acceleration issues and possibly disable hardware acceleration in Firefox ?
Options/Preferences -> General: Performance :
[ ] "Use recommended performance settings"
[ ] "Use hardware acceleration when available"

Close and restart Firefox after modifying this setting.

It was set on true but changed it to false. Does this mean I was choose to the test group or something?

Yeah already tried this but it didn't work

Not sure. Please let us know if disabling webrender (and restarting) made the glitches go away.

I will keep this updated but like I said this doesnt happen too often. Gonna wait a few days to see if the glitch shows up again

3 days after webrender disabled and the issue didn't show up so far. Gonna keep updating this in a few days and might call it fixed.

Okay almost one week and I haven't had the problem. I guess is fixed, hopefully I didn't jinxed it
