Created attachment 144810 [details] Pictures of over system vs other window SUMMARY I'm on an Acer Spin 5 with a 144 dpi display using wayland. The cursor scale is inconsistent. STEPS TO REPRODUCE 1. Using breeze cursor theme on Hi DPI display (144) 2. Move cursor from a chrome window (or Firefox, or spotify) to the desktop (or the system settings app, or krunner) OBSERVED RESULT Cursor becomes larger on system apps. EXPECTED RESULT Cursor size remains consistent SOFTWARE/OS VERSIONS Linux/KDE Plasma: Neon 5.23 User Edition (available in About System) KDE Plasma Version: 5.23.4 KDE Frameworks Version: 5.89.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION
Cursor size is set to 36 to reproduce. I had to reboot to update the size. When size is 48, the cursor is the same size on all windows.
Do you use fractional scaling (1.5x), right?

> Cursor size is set to 36 to reproduce. I had to reboot to update the size. When size is 48 Aha! This and the scale factor of 1.5x explains why the cursor is different. QtWayland scales the cursor size by the output scale factor. If the cursor theme has no the given size, it will pick the closest. Can you file a Qt bug report and link it here?

Unless you're as unversed in qt and c++ as I am, in which case I could start muddling through source code.
