Whole display is freezing, xfwm4 turning into disk_sleep

Hi guys

I have Debian with XFCE4 and I have a problem. Whole display is freezing every few seconds for a second. I've discovered that in htop there is xfwm4 process that turns state from S to D (disk sleep) when freeze occur. When I ran

strace -e trace=open,close,read,write,connect,accept xfwm4 --replace

command I've noticed that every time when it freeze it's closing and opening /dev/dri/card0 file. Not every close/open operation cause freeze, to make things clear. Exactly it looks like that

close(6)                                = 0
open("/dev/dri/card0", O_RDWR)          = 6

I have Lenovo Z51-70 notebook with CPU Intel Core i5-5200U with Intel HD5500 and AMD Radeon R9 M375. All packages are up-to-date, xfwm4 is in 4.12.4 version.

You might want to create a bug report against the xfwm4 product. The developer is quite active in responding to bug reports and may be the best one to ask about this.

Problem solved. In case anyone will have similar problem - turning V-sync off in xfwm4 settings helped.
