On my AROS 68k I have never had problems on the Pointer which completely disappeared, Apollo Team makes use of Dopus5 that creates could create that and other problems, you see slowness overlay icons
On AROS 68k the Pointer Preferences "doesn't support PNG images", but it supports very well the graphic pointers of OS3 RTG, on my AROS 68k I use the same pointers of my AfA One, as quality they are equal to those shown in the screenshot.
