After installing openSUSE Tumbleweed Snapshot 2025-05-22, I noticed that my mouse pointer started to duplicate after not moving it for a while. I tried disabling all other peripherals in order to isolate the problem, but it did not help. Today, I decided to change the size of the mouse pointer, and I realized that when it was below 36 pixels, this bug would occur. The default size was 24 pixels, and when I tried 30 pixels, the issue persisted, but when I increased it to 36 pixels, the problem was no longer present.
My monitor is 3840 x 2160 with 150% scaling enabled, and this issue occurs in both Wayland and X11 sessions. I believe it is a problem with my desktop environment. Does anyone know what could be causing this issue?
