Thanks for reporting this problem.

Unfortunately, I couldn't reproduce it.

However, I suspect this may be caused by switching to the smart 
scheduler by default in xorg-server 1.19.0-1.

So, the first thing I'd suggest you try is adding -dumbSched to the X 
server options to see if this makes a difference (e.g. 'startxwin -- 
-dumbSched'
