--- Comment #2 from postix <pos...@posteo.eu> --- Yesterday, short after I have posted the bug report and unlocking the session, the 3/4 (from left to right) of the Dolphin's titlebar on the secondary screen flickered, whereby the frequency increased when I moved the mouse on the secondary screen. Today, the whole secondary screen flickered after unlocking the session. It indeed happens occasionally. -- You are receiving this mail because: You are watching all bug changes.
