Firefox flickering after update 90.0.2

more options

Hi all After update 90.0.2 installed on my computer, FIrefox started flickering all the time a new page gets opened. I have never had such a problem before, nor I had any hardware change in the last two months. I tried several proposed solutions concerning flickering like refreshing, disabling hardware acceleration etc. but nothing helps. I wonder what happened in 90.0.2 which caused that. I just installed update 91.0 and the flickering still persists.

I am using Windows 7 Enterprise 64-bit on a Dell Vostro 3750 Laptop if that matters. Thank you

I know the OS is different, but have a look.

Thanks for this answer, yes the gfx.webrender.force-disabled = true solved my problem too. Not sure why I didn't find that question with the search, but thank you.
