16662	Unstable josm	acaiusa@…	acaiusa@…	"==== What steps will reproduce the problem?
1. Extended editing session, especially where memory usage approach max allocated for java 
2. Display start to lag when moving map
3. Keyboard input starts to be ignored. Mouse action still works (but cannot save session since cannot input file name. Work lost when josm is terminated. Not recoverable in the next session since it didn't find any crashed data layer. 

==== What is the expected result?
JOSM to continuosly function.

==== What happens instead?
Laggy display which eventually with keyboard input not registered by JOSM. 

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

my laptop: i3, 6GB memory. Linux detected 4 cores, during laggy display all 4 cores will go to 100%. When it goes down back to near 0%, then map-related action (moving map imagery, including tracing highways beyond edge of map) will resume working. Noticed this behavior since version 13996 when the imagery is interpolated for higher zooms (I think). 

Thanks and kind regards.
