I can reproduce that one, too. And actually, this already occurred with
other TOS versions in the past and Hatari has already a work-around
included for it (by not sending mouse movements within the first 10 VBLs).
Looks like 10 VBLs are not enough for TOS 2.06, but increasing it to 40
VBLs fixes the problem here, too:

Uwe, could you please check whether that patch helps with your problem, too?
