Bug ID: 419923 Summary: On dual screen setup (screen mirroring) the laptop screen sometimes has a time lag Product: plasmashell Version: 5.18.4 Platform: Manjaro OS: Linux Status: REPORTED Severity: minor Priority: NOR Component: Multi-screen support Assignee: aleix...@kde.org Reporter: gjwucherpfen...@gmx.net CC: plasma-b...@kde.org Target Milestone: 1.0 SUMMARY: On dual screen setup (screen mirroring) the laptop screen sometimes has a time lag. The external screen display (via HDMI) does not have this problem. The two screens are out of sync. STEPS TO REPRODUCE: Sorry, I still have no clue about how to reproduce this. I often observed this in Firefox while watching YouTube, but this is not limited to YouTube and Firefox. I have never seen this in other desktop environments. OBSERVED RESULT: The external Full-HD-display stays in sync, but the internal Full-HD - laptop screen freezes for several seconds. EXPECTED RESULT: There should be no difference between the content of the two screens.
