Premiere Pro - Input/ UI lag on M1 based systems using external display
There is noticeable input lag on m1 based Macs when using an external display. There are quite a few threads on the community forums.
I can replicate the issue on an m1 Mac mini and a m1x max MacBook Pro. Mouse clicks can take a few seconds to register.
Ive tested swapping out the cables connecting the display & connecting the display via usbc and hdmi.
The issue seems to be specific to the native version of premiere. There is no input lag when running the intel version of premiere through rosetta 2 emulation. Also, when switching back to the native version of premiere, the issue will be resolved temporarily but will reappear in a few hours.
It's also worth noting, there is no input lag when using the native version of media encoder, but there is input lag when using the same windows when exporting directly from premiere.
Hoping for a fix.
