[AMD/radeon] System slow on wayland, lagging mouse (but fast in Xorg)

[lotuspsychje]

Ubuntu 18.04 development branch @ 26/12/2017

Overall system is lagging when opening programs and mouse, not smooth to work with
on gnome and the default wayland session, the xorg session is fast without lags. Tested the same machine on 17.10 and have same issues.

updated system to 18.04.1 all to latest @ 7/8/18
lags are still persistent when launching programs mouse stutters
overall system lagging, moving mousearrow fast, it stays behind

xorg works fine & fast still

[Daniel van Vugt (vanvugt)]

The mouse movement logic in Wayland sessions is indeed different to Xorg. I'm working on it now. But this seems to be a duplicate of bug 1690719.
