When attempting to open coolercontrol-gui on Plasma 6 Wayland, no window is created.
The exact revision tested is 8110df5ad7abf5d4c0f6fb0f8f978390e77f9685
Both Wayland and XWayland/X11 have been tested.
QT_STYLE_OVERRIDE has been tested with both “Fusion” and “Windows”.
My system has no specific configuration related to chromium nor wayland, and themeing has been set imperatively through Plasma. The plasma install is just a basic plasma6.enable.
Here is the output of coolercontrol-gui –full-debug;
