--- Comment #3 from Holger <h.kl...@gmx.de> --- (In reply to Nate Graham from comment #2) > And all of these issues disappear if you turn off compositing with > Alt+Shift+F12? Yes, I confirm. Alt+Shift+F12 immediately stops the glitches and I could not reproduce them while effects are off. Especially susceptible seem applications, that use a combination of mouse-scroll and mouse-hover events: e.g. the mail list in Thunderbird: 1. scroll the list a few times up and down using the mouse wheel (exposing about 10 lines of hight for the list) 2. move the mouse a few pixel up, so it hovers a different mail-subject 3. e.g. the last line in the message list quickly toggles at a high frequency between two mails before and after the last scroll. The flicker continues about half a second after the last mouse-move and restarts, even if the mouse moves out of the window - but only as long, as it moves. I was suspecting other effects like transparency and invert, that I also regularly use, but I could reproduce without such a window on screen. -- You are receiving this mail because: You are watching all bug changes.
