Does it happen after you change the scale and reboot?
Comment 8 Vlad Zahorodnii 2021-05-14 19:36:06 UTC
Is this x11 or wayland? Also, iirc the auto cursor size was removed. Can you please check whether this bug is still present in 5.21 or 5.22?
Comment 9 amrith 2021-05-14 20:54:04 UTC
I will check if this bug is still present and update.

X11 , no idea about Wayland

The bug 416155 which is marked as duplicate has the issue on both although it doesn't have anything to do with scaling.
