--- Comment #24 from valdi...@gmail.com --- This is not fixed for me in 6.3.2, but now I have a somewhat reliable reproducer. 1. Open Telegram messenger 2. Open Firefox with the dark theme, maximize the window 3. Hide Telegram window behind the Firefox, DO NOT MINIMIZE THE WINDOW 4. Open this page (this bug), or for example https://docs.hackerone.com/en/articles/8399430-id-verification 5. Scroll the page slowly Result: 30 fps rendering, as shown by "Show FPS" desktop effect. This happens only when Telegram window is present on screen. It could be hidden behind Firefox, it could be visible, but it should not be minimized. Moving Telegram window to another desktop (not where Firefox is) does not trigger the issue. -- You are receiving this mail because: You are watching all bug changes.
