Failed Close Animation in Application Launcher when "Show desktop" is invoked.

SUMMARY
This is an issue that I have detected several years ago. 
When open Application Launcher and there are not minimized windows, the close animation of Launcher is soft, as the open animation.

But when “Show desktop” command is invoking, after open Application Launcher, the close animation is not soft when you click out the launcher; there is not animation indeed.

STEPS TO REPRODUCE
1. Open any window or windows.
2. Open Application Launcher and close (click in anywhere out the launcher). The animation close is soft.
3. Active “Show desktop” command using widget panel or hot corner.
4. Open Application Launcher and close (click in anywhere out the launcher). 

OBSERVED RESULT
When Show Desktop command is invoked, there is not close animation in launcher when you click out the launcher. Only works when you click again in icon panel launcher.

EXPECTED RESULT
Close animation when you click out the launcher, in any moment.

Works fine for me in current git master. Your screen recording shows a lot of other visual glitches too. Your panel is flickering a ton. What's up with that? Does this issue reproduce when using the default Breeze Global Theme?

That glitches are not an issue with Plasma Theme. Happens when use Vokoscreen and Tearing prevention is active, as Vokoscreen creator explain here https://linuxecke.volkoh.de/vokoscreen/vokoscreen-tips.html.

About my bug report, I don't know how to explain it, maybe is confusion from me about plasma behavior. Sorry.
