Such status code, very negative, so error handing, wow.

Is the bug still present? What is the output of xrandr?
Comment 2 Alexander Potashev 2021-07-12 19:35:20 UTC
According to xrandr, the refresh rate is zero:

```
$ xrandr
xrandr: Failed to get size of gamma for output screen

Comment 3 Vlad Zahorodnii 2025-01-10 13:13:07 UTC
Does Chrome Remote Desktop create a virtual desktop with 0Hz refresh rate? Can you run `WAYLAND_DEBUG=1 kcmshell6 kcm_kscreen` and post the log output here if the issue still occurs?
