SUMMARY

For the last ~month, I have encountered the following issue, which is a regression of some kind (I never observed it before). Eventually, after some days of use on a laptop, whenever I activate the search widget I get a very tiny little box just below the widget. Approximately 2x2 pixels.

It was only in documenting the issue for this report just now that I noticed that this box is actually resizable - it's the search widget! Somehow the widget has lost its natural size, and this condition continues until Plasma is restarted or the search widget is replaced on the panel. (Or, as I have just discovered, you resize the tiny widget back to something close to its original size.)

My best guess is that this is somehow related to switching from the external monitor to the internal screen, which is something I do a couple times per day. Despite my efforts I haven't been able to directly show this yet.

STEPS TO REPRODUCE
1. Put a search widget on your panel. I have it set to activate whenever I press CapsLock (Chromebook style).
2. Use your computer a bunch for a few days? Try using some external screens via USB-C?

OBSERVED RESULT

Eventually the search widget permanently resizes itself. The button for the widget is unaffected, and the widget continues to activate as before.


EXPECTED RESULT

No issue.
