16847	Tooltips glitches	lorenzo.beba@…	lorenzo.beba@…	"==== What steps will reproduce the problem?
1. Open JOSM for Windows (josm.jnlp, josm-tested.jar or Windows installer, it's the same)
2. Hold the mouse anywhere to make a tooltip appear (especially in the relation edit panel with downloaded members)
3. Move the mouse around to show much tooltips as possible (or wait enough, usually from 10 to 30 minutes of normal use)
4. All the interface will be a mess of repeated UI

==== What is the expected result?

The UI should always be usable.

==== What happens instead?

JOSM must be restarted to be used again because the UI is repeated randomly in every window when you pass the cursor over a button.

==== Please provide any additional information below. Attach a screenshot if possible.

On Debian and Ubuntu everything works right, even on two others Windows 10 PC (one of which with a dual monitor too). I've already tried to purge and re-install Java and also JOSM (deleting all files under the AppData directory). I've tried also with a clean version of JOSM (fresh download, without adding plugins or styles), but the glitch always appears.
