Window positioning broken. kf.plasma.quick: Exposed with no visual parent. Window positioning broken. kf.plasma.quick: Exposed with no visual parent. Window positioning broken. kf.plasma.quick: Exposed with no visual parent. Window positioning broken. xdg_surface#157: error -1: invalid window geometry size (0x0) qt.qpa.wayland: Could not create EGL surface (EGL error 0x3000) qt.qpa.wayland: Could not create EGL surface (EGL error 0x3000) This crash is not a core dump. Otherwise I would collect and debug it. It is always connected with external screen connected to the laptop. Not all of them. In this case it is a 4K screen and 150% fractional scaling. Other ultrawide screen connected the same through usb-c, without scaling is always ok. STEPS TO REPRODUCE It is not 100% reproducible. But it happens when the external screen goes standby and screen is locked. When I unlock the screen the panel is gone. OBSERVED RESULT The panel disappear and I need to manually start plasmashell again. EXPECTED RESULT SOFTWARE/OS VERSIONS Operating System: Void KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.2 Kernel Version: 6.6.52_1 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-8665U CPU @ 1.90GHz Memory: 15.4 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 ADDITIONAL INFORMATION It is not a new regression, I'm observing this from the Plasma 6 introduction (it may be present even before, but not in that frequent manner).

So far only see with AMD GPUs. See related NVIDIA bug 490813.
And also Bug 491844, which also has the same error message with an AMD GPU.
I observe similar issue on both of my systems. The second is older Lenovo T460 and when connected with HDMI it has a similar outcome as this bug. I need to clarify the error is the same, but probably is. None of these systems has a dedicated gpu. Both are wayland and Plasma 6.1.x.. I think I have also tested X11 on the older system, observing these random exits also. I will try to run the latest Neon on the older system to see if it is not a Void specific issue to sort that out. There may be something that a non-systemd system provides differently than the Plasma is expecting. And sorry for my initial description, that I forgot to erase the heading text. I'll be more careful next time.

Can confirm this on Plasma 6.2.2 and Qt 6.8.0. My laptop is connected to an external monitor with HDMI, and the laptop lid is closed and its monitor disabled. When the external monitor is switched off (typically when the laptop sleeps) and comes back on, the plasmashell panel is still there but renders as a black/grey bar with nothing visible. No mouse clicks on it will trigger anything, but I can still open the launcher and the clock/calendar using keyboard shortcuts. The logs described in this issue are there, such as "kf.plasma.quick: Exposed with no visual parent. Window positioning broken." When I open the laptop lid so that the laptop display turns on, the plasmashell panel "wakes up" and renders correctly, and the problem is solved until next time.
