displaying custom fonts sometimes fails #1

Open davervw opened 6 months ago

maybe the scanline interrupt is fragile, may have lost an interrupt, not to be seen again, stuck with ROM charset instead of switching between ROM/RAM/RAM which normally displays 3 different sets.

Workaround: cold restart system to reset VIC-II and load program again, load font again

having trouble reproducing this issue, unsure about it
