JIT Recompiler for ARM64 graphics issue

[benzo888]

Im using latest version of dolphin 5.0 on MacBook Air m1. Im trying to play Wallace and Gromit Project Zoo on gamecube and it loads in fine at 100% speed @ 60fps with no graphics issues at all until I get to the main menu where screen sort of flickers in a weird pattern and flickering increases when navigating through menu. When starting new game the cut scene has no graphic issue but when loaded into the game I can't see what's happening because of all the flickering and 'graphics loss'. When I change my cpu emulation engine from JIT Recomplier for arm64 to cached interpreter the graphics issue is completely gone but game speed is extremely slow ranging from 40% to 70%. Ive tried touching around in the settings but nothing changes.

Very interesting, I'll forward this around and see what everyone thinks of it.

Yes that's exactly what's happening for me, when you change the emulation engine it goes away but is extremely slow, please let me know if you find a solution, thank you.

It will take some time for us to investigate this.

If you just want to play the game at fullspeed for now, you can download 5.0-15146 macOS(Intel) and use rosetta. It doesn't have the issue and it is fullspeed on my macbook, at least at the start of the game. There are of course limitations with this approach, for example it may have some jitter and other quirks, but if you just want to play the game today, it'll do.

I tried the game on the dolphin version you recommended and runs fine with no issues, thanks a lot.
