Bug ID: 435114 Summary: redraw glitches over whole desktop with effects on Product: plasmashell Version: 5.19.5 Platform: Other OS: Other Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: k...@davidedmundson.co.uk Reporter: h.kl...@gmx.de CC: plasma-b...@kde.org Target Milestone: 1.0 SUMMARY Strange redraws with effects on. STEPS TO REPRODUCE 1. run plasma/kwin with effects on (Shift+Alt+F12) 2. use the desktop OBSERVED RESULT see video: first a Java-Program: TV-Browser, tooltips partially reappear, hover effects toggle by mouse-event, rightclick-menu heavily crippled second an arbitrary KDE program: Kate Line-highlight redrawn, scrolling the document blinks in frequency of the cursor, tabs shift back and forth to accomodate space for the * that marks a dirty unsaved file. Konsole running a command briefly prints its output and blanks back to black simulating the command was "undone", editing the line, previous lines toggle / simulate the last scroll up and down Dolphin slowly hovering the mouse from one file to another redraws the info-panel F11 not once for the new file, but toggles between the two for about 10 times, opening e.g. "Hilfe"-menu will also highlight "Einstellungen"-menu as though the mouse was over it EXPECTED RESULT The glitches shall not happen.
