eclipse - Java Swing program slows down over time in Ubuntu -
so made solitaire game java swing. tested on windows , mac osx , worked fine. then, installed ubuntu on macbook pro, , when run ubuntu, works gradually slows down, slowing down computer itself. using java 8 openjdk, running eclipse (although running terminal results in same problem).
here code:
