Bug Description
I often perceive massive screen corruption, most prominently in Firefox / GMail, but it may happen with any application, including terminals. Sometimes oversized letters appear. I run video stress tests, but they run without errors. I suspect the problem presents when many text needs to be rendered on-screen, as odd as it sounds.
I will attach screenshots.
