Description kdeneon007 2021-06-24 17:44:14 UTC

SUMMARY
Hovering over the mouse between different applets of system tray produces inconsistent and visually ugly transition. 

STEPS TO REPRODUCE
1. Place the cursor on any system tray applet.
2. Take the cursor to another applet.
3. Repeat this quickly.

OBSERVED RESULT
The transition is does not produce consistent result.

EXPECTED RESULT
The transition should be consistent. Probably a fade in or fade out effect should be rendered.

I'm getting the same issue when moving the mouse across the taskbar. And worse yet, I can end up with remnants of glitched tooltips on-screen, not cleared when you move the mouse away (see attachment). I was also able to create a black graphical corruption on the left side of the screen that flickered when I moved my mouse across the icons on the right of the panel, but I was unable to record or reproduce that issue, and it disappeared before I could launch a screen recorder.

Recorded a video of a corrupted tooltip icon, rendering in the wrong spot, scaled up from its original size, and flickering: https://www.youtube.com/watch?v=uicwjFR3du8

Not a System Tray-specific issue; this affects all PlasmaCore.ToolTipArea instances when using the Morphing Popups effect is used. See Bug 416048.

It did get worse/more noticeable with the adaptive Opacity feature, though.
