--- Comment #4 from bzz <bzz at atomicbee.cz> ---
weird story continues. I've switched cable HDMI - HDMI to HDMI - DVI-D (so
right now i cannot have full supported resolution by Dell U3014, but flickering
is gone and when i turn off and on display, i dont' have solid green screen. 

Is the HDMI or higher resolution problem? 

Anyway, i can still see warnings in dmesg:
