Bug ID: 380463 Summary: After switching to dual external monitor one of the screens are not refreshed Product: plasmashell Version: 5.9.5 Platform: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: Multi-screen support Assignee: aleix...@kde.org Reporter: kato...@gmail.com CC: plasma-b...@kde.org Target Milestone: 1.0 Created attachment 105844 --> https://bugs.kde.org/attachment.cgi?id=105844&action=edit Screen record of the problem I use my notebook either with its own screen, or with two external screens with the own display switched off. When I connect the two external monitors, the system changes to the correct setup (side by side screens), but one of the screens do not refresh, the windows are shown as they were on the notebook screen (both the notebook screen and the bad screen are FHD), but the screen is practically frozen. However not fully, since the mouse pointer is visible and moves, and it can also interact with screen elements and windows, but the screen is not refreshed at all. I can even grab a window and move it to the other screen, which results in a strange layout of having the live window on the good screen, while having the original window on the bad screen. I have tried to make a screen record with SimpleScreenRecorder. The recording is also strange, because it shows that the screen is somehow refreshed, but sometimes it flickers back to the frozen state. This strange behavior can be solved by either switching to a terminal screen and back, or by disabling the bad screen and re-enabling it. When everything is ok, the screen recording is fine, no flickers (thus it is not a software effect), so I attach the recording to illustrate the problem. This whole problem started a few weeks ago, but do not know exactly which KDE version is the starting point. -- You are receiving this mail because: You are watching all bug changes.
