Bug ID: 458622 Summary: Window order gets briefly switched when changing workspaces, when a window is set to appear on all desktops Product: kwin Version: 5.25.4 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: compositing Assignee: kwin-bugs-n...@kde.org Reporter: adam.m.fontenot+...@gmail.com Target Milestone: --- Created attachment 151775 --> https://bugs.kde.org/attachment.cgi?id=151775&action=edit screen recording of the problem SUMMARY When you have a window open on workspace 1, and another window open on workspace 2, a third window that is set to show up on all desktops will briefly pop up above the other windows, before (spontaneously) finding its correct order a second or so later, every time you change workspaces. This is *extremely* irritating and should be easy to reproduce. The bug is probably somehow related to https://bugs.kde.org/show_bug.cgi?id=455429 but it's not the same issue. I don't have "slide back" enabled. Note: I'm using "workspace" and "desktop" synonymously in what follows. KDE is not consistent in how it describes this concept. STEPS TO REPRODUCE 1. Open a window on workspace 1 and another window on workspace 2. 2. Open a third window and use the window actions to put the window "On All Desktops". 3. Toggle between the workspaces and raise the windows you created in step 1 so that they're above the third window in the order. 4. Toggle between the workspaces. OBSERVED RESULT The third window (created in step 2) that is set to open on all desktops will briefly "flash" above the other windows when you change workspaces, even though it should be at the bottom of the stack on both workspaces. After a brief (~1s) period, it will then drop down below the other windows to its correct order. Windows set to appear on all desktops will briefly flash above even windows that have "keep above" set. Changing the Virtual Desktop Switching Animation to "Fade Desktop" instead of "Slide" does not fix the problem. It's a little harder to detect because the animation is faster, but definitely still happening. EXPECTED RESULT Windows should stay at the correct order when switching workspaces. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.97.0 Qt Version: 5.15.5 Kernel Version: 5.19.5-arch1-1 (64-bit) Graphics Platform: X11 Graphics Processor: Mesa IntelĀ® HD Graphics 3000 ADDITIONAL INFORMATION I'm about 90% sure I saw someone report this issue on the KDE subreddit around the time 5.25 was released, but I can't seem to find it now. I think this is a regression in 5.25 but I'm not certain about that. At the very least it's a regression over ~6 months ago. -- You are receiving this mail because: You are watching all bug changes.
