I don't think this has always been the case, but I'm not 100% sure. For me, this is reproducable very easily if I view some large (3000x2000 pixels) .jpg files in konqueror. On my 6.2 system, memory usage goes up quite a bit while decoding the image, then it drops a bit. If I close the image, memory usage is normal again. On my current system, sometimes memory usage goes up very high when opening an image and doesn't go back to normal, even if I close the image. It only goes back to normal if I close konqueror. Note that I see this also with a gtk app, so this is not a KDE bug. Also, at least in konqueror, I can reproduce this with .png files, so it's also not a jpeg library bug. CURRENT and ports on both systems are up to date. I don't really know what's causing this problem. Maybe it's related to jemalloc, but I'd be surprised if no one else has noticed this before. size/res values reported by top 6.2 desktop pc with nvidia binary driver konqueror 40M/30M CURRENT notebook with the i810 driver konqueror 290M/250M Any clues or more information needed?
