Hi, I noticed about a week ago that when I would have Firefox windows open on more than 3 of my displays, the newest window, when maximized, would appear with white bars. This does not occur when Windowed or when troubleshoot mode is on. I have attached a photo of the error (suggestions omitted for my own privacy). Bugged window does not respond in this state and cursor does not blink etc. Other Firefox windows work fine. I'm running a custom color scheme, Dark Reader for Firefox, and AdBlock for Firefox. Issue does not occur with Chrome or Edge, which have the same, if not more extensions loaded. Glitch presented itself near the beginning of November. Please help! I'll check on this every once in a while, and am willing to run tests.
