SUMMARY
I have a hybrid graphics laptop with amd integrated and nvidia discrete
graphics chips. Recently i've noticed when i'm on Wayland if i launch mpv on
the amd integrated graphics the action to resize window on kde wayland is super
slow. This does not happen if i launch mpv with xwayland. This also does not
happen if i launch mpv with Wayland but on the nvidia chip. 

I also tried this on Gnome and with Gnome Wayland on the amd graphics chip this
bug is no longer present. I'm not sure if this is a kwin bug but i wanted to
report this since this only seems to happen on Plasma Wayland.

mpv is running on the gpu with the waylandvk context. there is also nothing in
the logs and cpu usage is not going up.  

STEPS TO REPRODUCE
1. launch mpv on an amd graphics chip like the amd Rembrandt
2. try to resize the window 

OBSERVED RESULT
resize is super slow(even though it's smooth)

EXPECTED RESULT
resize is fast and keeps up with mouse
