Hey there,
I just installed manjaro 18.1.0rc8
and experienced some weird rendering with xfce.
As soon as I plug in an external display via HDMI (which may not be exclusive cause here though),
there are contrasty squares all over places which have recently be changed/painted (by the compositor, seemingly).
See the following photo:
I managed to resolve this issue by disabling XFCE's Window Composition in the Manjaro Settings.
It eversince does render window contents properly, yet without any window transparency.
Should I address this issue at XFCE forums, or is Manjaro the right place for this?
Does anyone have a hint to what might cause this issue?
It may be related to the new XFCE 4.14 release whose packages came along an initial package update.
I also just wanted to post this issue somewhere so people may google it
