--- Comment #3 from Martin Gräßlin <mgraess...@kde.org> --- How do you suspend the system? Can you please provide the output of: qdbus org.kde.KWin /KWin supportInformation Please note that the screenlocker does ensure that the screen is locked prior to suspending. We have cases where incorrectly one frame is shown by the GPU driver, but a case like yours has not been described in years and I spent days ensuring that this cannot happen. -- You are receiving this mail because: You are watching all bug changes.
