Game WoW broken in 10.15 & HaC 2.6 Intel/AMD

[lmshsqlc]

Describe the bug
The game World of Warcraft cannot load into game interface after selecting character in 10.15. After selecting my character and loaded into game(when it should be), The game interface is fully grey/red.
Meanwhile the whole system goes not responding including audio output, mouse click & keyboard input except mouse movement. every 10 to 15 secs the system responds to what was input during the period and audio plays for around 2 secs. It will reboot itself within 1 minute (if I don't try to stop the WoW process).
I've tried repair the game, re-installed macOS Catalina, tried WoW starter edition and switching between Clover&OpenCore, used DeviceProperties instead of ACPI Patch. nothing works in 10.15. Googling and nothing similar.
the only thing I'll suspect is maybe the graphics handles differently. And I also saw an issue #42 . maybe there's something to do with that.

Expected behavior
The game should have loaded into the correct state just like in Windows and was in 10.14 before. League of Legends EUW works just fine.

Panic log

This is what it looks like when it starts to lag.

This is what it looks like when I try to end the process.

After ending the process I can smoothly control the computer again.

I think it’s trying to decode encrypted video. I get the same behaviour (red screen, system super slow) trying to play an iTunes video with hw drm and WG patches disabled.
