Bug ID: 383179 Summary: KDE desktop compositing occasionally causes flickering and frozen window contents Product: kwin Version: 5.10.4 Platform: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: decorations Assignee: kwin-bugs-n...@kde.org Reporter: sonichedgehog_hyperblas...@yahoo.com Target Milestone: --- KDE desktop compositing occasionally causes strange visual artifacts. This includes the following problems, which may or may not be related: - Certain panels flicker when rendering against other panels, which looks as if the two are z-fighting. I often see this with Skype notifications in the system tray as they interfere with the Plasma panel. - The Plasma desktop no longer executes visual updates unless the user does an action that forces it to. For example: If you have an analog clock with the seconds hand enabled, you will notice that it's stuck and the hands aren't moving any longer... however if you switch desktops to force a redraw, the hands will move to represent the current time but only once at that moment. This problem is rare and always goes away after toggling desktop compositing. - The contents of certain windows are no longer updated, and a past version of the window is drawn instead. I often think the application has frozen until turning off desktop effects and seeing that it updates again. This problem is rare and always goes away after toggling desktop compositing. Since I don't know how much this is a KDE problem and how much it's the drivers, I'm reporting it with both of the teams. My OS is openSUSE Tumbleweed x64. Plasma 5.10.4, MESA 17.1.5, Kernel 4.11.8. My CPU is an Intel core i7 920, my video card is a Radeon R7 370 from Gigabyte (RadeonSI / GCN 1.0 / Pitcairn Islands) and I'm running the 'radeon' driver (no 'amdgpu' support yet). -- You are receiving this mail because: You are watching all bug changes.
