GUI hangs when some OpenCL application was intensively working

[matszpk]

Hi, I have new troubles with new Radeon Crimson drivers on new OpenSUSE 42.1 distro.
I encountered numerous GUI freezes when OpenCL application was working intensively (I am crunching BOINC project: POEM with my GPU).
I am using KDE 5 Plasma and that error was, when I am using openGL 2.0 Compositor. When I am using XRender compositor that error encounters much rarely.
Kernel logs:

My config: Radeon HD 7850, Core i5 3470.
This same behaviour have been observed when an OpenCL app is working on the overclocked and stock GPU.
Any suggestions to solve this problem?
