Performance issues over USB 2.0 on Manjaro Gnome Wayland

[pedrodejesus]

Hi folks!

I'm using a MacroSilicon adapter for HDMI which claims to be USB 3.0, but in reallity is USB 2.0.

I tried everything I could to enhance its performance, like moving from xorg to wayland (it actually helped a little), reducing the monitor resolution and framerate, etc. But, unfortunately, it's still having some visual glitches (for example when I open an application on the adapter monitor).

I know that over USB 2.0 the frame transfer rate is slower, but is there anything else that I can do, or even some applicable change to the driver code, that would help me fix this problem?

Thanks a lot in advance!

Hi, thanks for sharing your experience. I recommend you try this version of the driver at https://github.com/tiirwaa/ms912x to see if the performance improves and the screen tearing is fixed. I’m working on some optimizations that might help with those issues. Let me know how it goes!
