Created attachment 162244 [details] Captured frame of flickering When configured in autohide mode (full width or floating), The Taskbar flickers. The flickering is noticable when the desktop is configured to use darker background (wallpaper or solid color). The flickering is noticable both when the user moves the mouse to the bottom to make appear the Taskbar as well as when the Taskbar is in the process of hiding. STEPS TO REPRODUCE 1. Configure your desktop to use a darker solid color or wallpaper (The default KDE plasma 5.27 will do fine). 2. Configure the Taskbar to use autohide mode (classic full width or floating panel). 3. Move the mouse to the bottom of the Desktop to make the Taskbar appear, or, move the mouse to the center of the Desktop to make the Taskbar hide. OBSERVED RESULT There is noticable flickering. EXPECTED RESULT Expect not to see flickering.

I'm not able to reproduce this issue with those steps. Do you think you could attach a screen recording or a phone video that shows the issue? Thanks!
I made a video with my phone, but it is 102 megabytes. Where can I upload it given that here uploads can only be 4000 KB max.

Be sure to watch the video at 1/4 speed.
Thanks. Cannot reproduce in Plasma 6 Wayland with a dark bottom auto-hide panel. Can you reproduce the issue if you reduce the global animation speed to something very very slow on System Settings' Quick Settings page?
I reduced the speed to minimum and the issue is even more visible. Animation speed does not cause this issue except for the fact that if you configure Plasma for maximum animation speed you will probably hardly notice it. As I wrote this issue is not present if the background is bright, for example, if I choose Kay wallpaper or set the background to solid white. Check the video it at https://streamable.com/r8dmp8
I did some other modifications to visual settings and found out that this is a issue limited to "Breeze Dark" Plasma style.
Interesting. I cannot reproduce the same thing with a slow animation speed in Plasma 6 with Breeze Dark. A lot of changes have been made to how panels work and animate, so let's call it fixed in Plasma 6!
