I think we have this fixed in current upstream kernel. Please try v4.3-rc. If the problem persists with latest kernels, please file a bug at the freedesktop.org bugzilla [1], referencing this bug. Thank you. [1] https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Intel
Thanks, I'll check it out and report back in case it doesn't work! Cheers!
