For grouped tasks (several instances of the same application) one of the thumbnails in the tooltip is duplicated.
Broken in b40c0de099fc951dbe3423b99310e7c7f799c8c4
More info: this only happen after killing and restarting plasmashell. In a new session it works fine (until you restart plasmashell).

Created attachment 110799 [details] Screenshot I see this also. New sessions are OK, but it's there after you kill and restart plasmashell. Also, if you click the close button on the phantom item, all the windows close.

Small comment: sometimes it also happens without plasmashell crashing beforehand, and also happens sometimes after kwin crashes rather than plasmashell.
I'm also affected by the problem. The duplicated thumbnail has no title, no effect. It's not always the same and can be an icon or the thumbnail of another application. With Plasma 5.12.2
The problem is also reported here: https://bugs.mageia.org/show_bug.cgi?id=22715 For me, I don't observe any scrash. This behavior occurs since the start of the session. I don't understand why the status is still unconfirmed.
I can no longer reproduce this in 5.12.5 (Frameworks 5.46)
Me neither, nor with Plasma 5.13 and Frameworks 5.47 (both built from source). Let's call this fixed and re-open it if we get any other reports from later versions.

Fix tooltip woes Summary: Users have reported a number of bugs against TM tooltips, e.g. initially coming up with crazy sizes, or showing window duplicates. This all comes down to a race conditions causing stale data and ugly code that's using visible props to swap between two alternate UI implementations instead of doing clean conditional loading. With this cleanup patch the problems should be gone, as well as various ReferenceErrors spewed onto the tty.
