Bug ID: 407024 Summary: Panel texture flickering Product: plasmashell Version: 5.15.4 Platform: Kubuntu Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: k...@davidedmundson.co.uk Reporter: andy...@mail.ru CC: plasma-b...@kde.org Target Milestone: 1.0 SUMMARY I noticed texture flickering in a few cases. STEPS TO REPRODUCE Scenario 1. 1. Create a horizontal panel with a few application icons. 2. Move the mouse over the icons on the panel. Try moving fast enough so that tooltips with the icon name don't appear. Scenario 2. 1. Invoke logout/reboot/shutdown effect. OBSERVED RESULT Scenario 1. The panel texture is flickering. I can see its opacity vary, as well as contents jitter during the flickering. Scenario 2. The screen dimming effect of the logout/reboot/shutdown animation has flickering opacity. After the animation completion, sometimes the effect darkens the desktop contents more than usual, and then after a fraction of a second (or maybe after I move the mouse) opacity gets restored to usual (which looks like desktop contents become less darkened). While the animation is in progress, the logout/reboot/shutdown icons flicker. EXPECTED RESULT No flickering should happen. SOFTWARE/OS VERSIONS Linux: Kubuntu 19.04 KDE Plasma Version: 5.15.4 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.2 Mesa: 19.0.2 X.org: 1.20.4 ADDITIONAL INFORMATION I'm seeing this on a laptop with Intel Haswell iGPU (i915 driver). I've also seen the problem with logout/reboot/shutdown effect on a different machine, also with Kubuntu 19.04, but with Nvidia GPU (430.09 driver). Not the panel flickering, though. -- You are receiving this mail because: You are watching all bug changes.
