--- Comment #2 from Piotr Mierzwinski <piotr.mierzwin...@gmail.com> --- Maybe this is matter. My monitor is connected by DVI link. Additionally between monitor and DVI there is also adapter: HDMI->DVI. Issue not happens when I turn off monitor (when screen is locked), and on it again. -- You are receiving this mail because: You are watching all bug changes.
