[SOLVED] Disturbing Glitches on ATI/Intel Hybrid Graphics

Hi forum,
I have Samsung notebook with two graphics cards. I use open source drivers. But I when run any application with DRI_PRIME=1, its look like this:

My system:

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series] (rev ff)

$ uname -a
Linux HELYX 4.5.0-1-zen #1 ZEN SMP PREEMPT Tue Mar 15 18:33:17 UTC 2016 x86_64 GNU/Linux

$ pacman -Q ...
xf86-video-ati 1:7.7.0-1
xf86-video-intel-git 2.99.917.631.gf2a4645-1
mesa-git 11.3.0_devel.80247.f30f6e2-1
lib32-mesa-git 11.3.0_devel.80247.f30f6e2-1

Any idea? (Sorry my English)

UPDATE: Glitch problem solved when I edit /etc/X11/xorg.conf.d/20-intel.conf like this (disabled dri):

Section "Device"
    Identifier "Intel Graphics"
    Driver "intel"
    Option "DRI" "false"
EndSection

But that's get poor FPS. 10-15

UPDATE: SOLVED! "VSYNC fix this problem"
