Text input eventually stops working

[AntiCompositeNumber]

After some time using JOSM normally, all text fields will stop reacting to input. Keyboard shortcuts and controls still work normally. Text fields do not react when clicked on, can not be pasted into by keyboard shortcut or context menu, and can not be typed into. This usually happens about 2 hours into an editing session and happens reliably. It does not appear to be associated with any particular action. The workaround is to restart JOSM. I did not observe it while running with --debug, but might not have waited long enough. I'll try for normal logs later. This issue appeared recently, after switching from josm-stable (18646) to josm-svn (18676). It also happened on 18662.

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