kwin flickering when compositing through opengl

Hi,
has anyone experiences on the following bug? I just filed it:
https://bugs.kde.org/show_bug.cgi?id=384660

I suspect it is "triggered" by a dual-head setup, and i've always had this problem, but now that i switched my gpu from nvidia to integrated intel and it is not gone, i suspect it is time to blame kwin!

Re: kwin flickering when compositing through opengl

Any non default i915 parameters? Or rather lack thereof? Im thinking along the lines of https://wiki.archlinux.org/index.php/In … flickering

Re: kwin flickering when compositing through opengl

The issue was present even with the nvidia proprietary driver, so i'd exclude anything related to the chip or the video driver, and it is not properly a flicker, but more "flashing":

Thanks seth, trying just now.
The issue is present randomly, so i need to test it more, but by now it seems good.

-EDIT-
Unfortunately the issue is not solved sad
