Created attachment 153776 [details] System log from the timeframe of screen wake SUMMARY This issue occurs after waking the screen after it has turned off (due to Screen Energy Saving) - *not* from Suspend session (when manually putting computer to sleep). Some application windows (though not always all) seem to disappear. The application is still running and its icon is still in the Task Manager. However, clicking the application icon in the Task Manager does not bring the window into view. I end up needing to close the windows from the Task Manager (window preview pane shows blank window as well). Then I can re-launch the application. I see in the system log (attached), that there is this message from the time when I wake the screen: kwin_wayland[14813]: libkwinglutils: Invalid framebuffer status: "GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT" STEPS TO REPRODUCE 1. In System Settings, Power Management, Energy Saving, enable Screen Energy Saving and set time to some value < Suspend Session time. 2. Wait for screen to turn off as per time set in step 1 3. Wake the screen by pressing key on keyboard OBSERVED RESULT Some windows that were open and visible before the screen turned off - such as Konsole - are no longer visible. However some other windows are unaffected - such as Firefox. I'm unable to find a pattern as to which windows will disappear and which won't, but Konsole seems to be reliably reproducible. EXPECTED RESULT All open and visible windows before the screen turned off should be present when the screen turns back on. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Fedora Kinoite 37 (available in About System) KDE Plasma Version: 5.26.2 KDE Frameworks Version: 5.99.0 Qt Version: 5.15.6 ADDITIONAL INFORMATION GPU: AMD RX 6900XT connected to 4K monitor using DisplayPort

Created attachment 153778 [details] After screen wake 1 This is what my screen looked like right after waking it. All my windows have disappeared.
Created attachment 153779 [details] After screen wake 2 There was a crash report from System Settings, and you can see that other applications that were on screen prior to the screen turning off (Konsole, KWrite) are still running in the Task Manager. However, the window preview is blank, showing the window is gone.
Updated system to following versions; issue still remains: KDE Plasma: 5.26.3 KDE Frameworks: 5.100.0 QT Version: 5.15.7
When it happens, can you open the kwin debug console (search for kwin in krunner) and check the geometry field for the disappeared windows, if they're offscreen or resized impossibly small, something like that?

Hi, I've uploaded screenshots of the Kwin Debug console, opened to the Konsole windows that has disappeared.
> geometry: 8267.5,8267.5, 8268x8268 Couldn't be weirder but that explains why you don't see the window anymore
Hello, I am also having this issue. It is still present in 5.27.2 Operating System: Fedora Linux 37 KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.15-200.fc37.x86_64 (64-bit) Graphics Platform: Wayland However sinc e5.27 the window can now be recovered by focusing, defocusing, refocuing the window (click on the app in the task manager) Won't work if multiple windows are grouped in task manager. If any debug output or testing is needed, please feel free to ask
Something that might help. On my laptop, in don't have the issue. It's configuration: Operating System: Fedora Linux 37 KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.15-200.fc37.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-8565U CPU @ 1.80GHz Memory: 15.4 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 Manufacturer: ASUSTeK COMPUTER INC. Product Name: ZenBook UX433FA_UX433FA System Version: 1.0 On my desktop, it is pretty systematic when waking up the screen (single screen). It's configuration: Operating System: Fedora Linux 37 KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.15-200.fc37.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 1600 Six-Core Processor Memory: 15.6 GiB of RAM Graphics Processor: AMD Radeon RX 5700 XT Manufacturer: Micro-Star International Co., Ltd. Product Name: MS-7A39 System Version: 1.0 The desktop has a 4k resolution but event in 1920x1080 the issue is present. So it looks like an issue with AMD GPU.
Created attachment 167981 [details] before sleep with quick tiled windows After upgrading to plasma 6 on Fedora 40 Beta, the situation is much better. Operating System: Fedora Linux 40 KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.8.2-300.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 5600X 6-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: AMD Radeon RX 5700 XT Manufacturer: Micro-Star International Co., Ltd. Product Name: MS-7C91 System Version: 2.0 The issue appears to be fixed for floating windows. I just ran a few sleep/wait/resume and the windows come back with the original geometry. However the geometry changes when windows are quick tiled. (which is my regular way of organizing my windows :/ ) The title bar comes back to a original (default) size and the body of the window either keep the pre-sleep size or reverts to an original size matching the title bar. I hope this helps to pinpoint the source of the issue.
