Been occurring fairly frequently since I installed a new video card a few days ago. The blocks tend to disappear if I open another tab so not sure if it's a driver issue or something wrong with the installation. Any ideas?
firefox is up-to-date, don't use it for games and haven't really used any other applications in the past week or so. tried re-installing video card but seems issue hasn't gone away :/ has anyone seen something similar occur above to them and how they did fix it?
