Graphics / Timing Bug? #687

Closed MeAndMyRhythmbox closed 3 years ago

MeAndMyRhythmbox commented 3 years ago

This lovely image from the Gubbdata 2021 compo is not displayed correctly - has flashing white background. Wonder if it's just me or perhaps this is a useful test case?

Changing VIC chip version in hardware preferences produces additional glitches in left and right borders for some settings.

... the web version of virtualC64 seems to be working correct ?

@MeAndMyRhythmbox I do not see any flashing in the white background here ... maybe it is related to the metal rendering of your specific mac machine ? Please try the webversion link above to check this ... the webversion uses webgl instead of directly pushing into the metal API ...

If the glitches do not appear in the webversion on your machine ... then this issue in vc64mac is likely not related to the emulation core but maybe to the metal swift rendering layer of vc64mac ... what machine are you using ? do you maybe use a hackintosh 😬
