i was having i think the same issue, though i’d like to add that i was also experiencing some overall text fuzzyness in every aspect of the browser, browser settings included. a google spreadsheet when scrolled would often leave a previous frame or two overlapping with the new, making some extreme visual bugginess. i think this was what was happening with the text to make it fuzzy sometimes, like i had mentioned.
But, i think its fixed now!
the option that fixed it was 4. option 3 made it to where my whole screen flickered non-stop. when I chose OpenGL in the drop box from option 4, everything started working properly.
thank you @Saoiray , this had been bugging me going on 1-2 months since it randomly started after a long time of no issues!
