After updating my graphics card driver and switching from a 60Hz main display to a 120Hz display, Firefox became very slow and unresponsive. Text is also rendered weirdly, and no amount of ClearType correction does correctly fix it.
The monitor displays text in images and videos as well as text from other applications correctly. Moving the browser window to any of the other three connected displays, all running in 60Hz mode, does not fix either issue.
I've used Google to search for similar problems and tried multiple possible solutions, like disabling HW acceleration and restarting in safe mode, but sadly none of those worked.
I've appended a screenshot from https://www.typetester.org that shows three different fonts. It should be obvious that neither the examples, nor the default font of the site, is rendered correctly, although the example to the far left doesn't look as bad as the rest.
EDIT: Added another screenshot, this time an excerpt from a Wikipedia article. This shows that the kerning is all messed up (CMMI looks more like CMVI) and somehow cursive font is rendered almost correctly.
