Bug in input helper design
This problem has been happening very often even though I deactivated the skins. You could do something to force an update and refresh on the painting, the problem happens as I type.

I also have this bug. It happens when you have less item count than the window can hold. For example, you have 5 matching items, but the window height is larger, so the rest area will be filled with garbage. Sometimes it's just a black area, sometimes it draws a part of your source code from another place. Buttons on the right side also have black background. I have 150% screen scaling (144 PPI) if it matters.
