Created attachment 174185 [details] Screen picker shows blank entries after updating to Qt 6.7.3 SUMMARY After updating from Qt 6.7.2 to 6.7.3 the screen picker in system settings shows 2 additional blank entries instead of just the screens that are actually connected to the GPU. This did not happen with Qt 6.7.2. STEPS TO REPRODUCE 1. Update to Qt 6.7.3 2. Open "System Settings" 3. Open "Display & Monitor" 4. Click on the drop down control labeled "Device" OBSERVED RESULT It shows 2 additional blank entries instead of just the screens that are actually connected to the GPU (see attachment). EXPECTED RESULT It only shows the screens that are actually connected to the GPU and no blank entries like it did on Qt 6.7.2. SOFTWARE/OS VERSIONS Operating System: EndeavourOS (Arch Linux) KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.3 Kernel Version: 6.10.10-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7800X3D 8-Core Processor Memory: 30,9 GiB of RAM Graphics Processor: AMD Radeon RX 7900 XTX

This is actually caused by a bug in the Linux Kernel 6.10.10. 6.10.11 fixes it.
Updated to kernel 6.11.1 now and the issue is still there. So either the fix from 6.10.11 is missing there or it is not the same issue.

The issue persists on kernel 6.11.5, Plasma 6.2.2 and QT 6.8. I don't think it is a kernel issue.

Some investigation by others has revealed that this is caused by the same Qt regression that caused Bug 493116. Happily, it's already fixed in Qt 6.8.1. Bug your distro to backport the fix!
