18427	JOSM consume 100% CPU for no apprent reason	francois.lacombe	team	"==== What steps will reproduce the problem?
This issue occurs often on my computer, but really hard to reproduce.
It can independently happen when editing with several image layers and plugin or on the welcome screen with several minutes of idle activity.

==== What is the expected result?

JOSM shouldn't consume 100% 8-core CPU full time

==== What happens instead?

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