I have a bug that drives me crazy...

This does not work (the last 128:th write is not scaled *2):

ori #$8,mr
move y:(r5)+,a
do #127,_loop
move a,y:(r7)+
move y:(r5)+,a
_loop: move a,y:(r7)+

This works but i shouldnt have to enable the scaler twice(?):
ori #$8,mr
move y:(r5)+,a
do #127,_loop
move a,y:(r7)+
move y:(r5)+,a
_loop: ori #$8,mr
move a,y:(r7)+

This also works (as it should):
ori #$8,mr
do #128,_loop
move y:(r5)+,a
move a,y:(r7)+
_loop:

Im on Hatari 1.7.0 (windows), QASM. Any ideas/comments? (I don't have access to the real Falcon atm)
