Description n3rdopolis 2019-01-04 01:31:18 UTC 
Hi

I am not sure of what information to provide since I am not sure how the internals of kwin_wayland works. 

But trying to run kwin_wayland with master xserver, and it hangs, running it with GDB, and IIRC it hangs trying to connect to the display. (and it deadlocks pretty hard, where it ignores CTRL+C)

I narrowed it down to commit 08843efc5940563a2275c654804c999cfc772987
the commit before, and kwin_wayland runs fine

Thanks

https://gitlab.freedesktop.org/xorg/xserver/merge_requests/99 claims to fix this.

P.S. Xwayland bugs should be filed at https://gitlab.freedesktop.org/xorg/xserver/issues/new now.
