Comment (by jonas.kirilla):
It's likely an effect of the accelerated drawing functions not being used
currently. Additionally the cursor isn't a hardware cursor and thus
causing redraws as you move it around. IIRC Haiku works better on more
recent hardware with the app_server changes that prompted the turning off
of the accelerant functions, and the drawbacks on older hardware was
deemed as no big loss at the time. (Was it double-buffering?)
There was a discussion on it, which I haven't found, but maybe this will
get you started:
