Description Dmitry Kazakov 2013-08-27 09:58:37 UTC

1) Create an image, say, 5000x5000px
2) Add several layers
3) Switch current layer

Every switching takes several seconds on Core2Duo CPU

Hm... On my desktop it still takes only a second for a 10k x 10k image, but that's pretty slow already. I don't think a whole lot changed there recently, though. Maybe git bisect can help?
