Dragging window very slow and random freezes on RPi4

[Brevan960]

I have a Raspberry PI 4 and when I try to connect to a pc I get really bad performance I’ve tried to disable multi-pass display encoding and have tired disable frame buffering on decoding and disable client-side image post-processing and have tired different encoding option (VP8, H264, MJPEG) and I don’t know what to try next

I’ve even tried overclocking the pi and running both 32bit and 64-bit Raspberry PIOS.

The type of lag I’m getting is: when I drag a window it takes a very long time to show the changes and just freezes for like 1-2 seconds at random times and massive v-sync issues

As stated before I’m using a Raspberry PI 4 with an ethernet connection and I’m connecting to a macOS Host and when i connect to it using a different pc it works fine

Any help is appreciated,

Thanks.

Hi, RPi4 as a desktop client most likely is not the best choice. If you’re using it to run a Youtube video, for example, with Raspbian’s own Chromium, CPU usage can reach 100%.  Whereas if you use a PC to connect, there are no issues whatsoever. We are planning to support GPU accelerated decoding on RPi in the future, so watch out for that.
