seemingly at random, images displayed in firefox will look incredibly messed up (like artifacting, and discolored chunks or stripes), text will be missing (as small as a few letters or as much as a page having no visible text at all), text will be discolored (usually a bright color like neon green or pink), and/or or text will appear blocky (sometimes manifesting as the font looking a little thicker and less HD, sometimes as bad as just being illegible rectangles). text with missing letters is able to be read while highlighted, but text that has become blocky is still unable to be read (still blocky) even while highlighted. i don't know if discolored text is affected by highlighting.
these issues happen regardless of what website i'm on, and will also happen on new tab pages or on firefox settings pages. it isn't consistent, it comes and goes. refreshing the page doesn't help or change anything, but if i close the tab and then navigate to the page again it's often different.
i've attached all the examples i've thought to capture, which isn't much. it can make the browser practically unusable at times.
i have firefox version 89.0 (64bit, auto updates enabled), on a windows 10 with 8GB of RAM and AMD FX-9800P RADEON R7 (i honestly.. don't know what that part means, but thought it could help) i previously had "Use recommended performance settings" and "Use hardware acceleration when available" enabled in firefox, but i turned them both off in an attempt to fix the problem. it didn't help.
i can't say for sure when this issue began, as i haven't used firefox much until recently, but i think it's been happening for over a month now. none of the other programs i use appear to be having visual problems, just firefox. at some point a year or more ago, i ran firefox on this computer without issue.
