mikaelhc Posted February 3, 2009 Author Share Posted February 3, 2009 First, let me thank you for a wonderful program. I have a single issue: When I make a large rectangular selection (e.g. Select All (Ctrl+A)), the CPU Usage climbs to >30% and stays there. This is annoying, because I often paste screenshots from the clipboard, and if I forget to close Paint.NET, it will keep using the CPU in the background. Isn't it possible to paint the 'cycling' selection without draining the CPU? (Or stop the cycling effect, when the App looses focus?) Best regards, Mikael. Btw: This happens on Paint.NET 3.36 (and earlier). It is probably mostly noticeable on slower, single-core systems. Quote Link to comment Share on other sites More sharing options...

Bob Posted February 3, 2009 Share Posted February 3, 2009 if I forget to close Paint.NET, it will keep using the CPU in the background.Isn't it possible to paint the 'cycling' selection without draining the CPU? (Or stop the cycling effect, when the App looses focus?) Minimizing Paint.NET send the app in a "low-profile" mode. Notice that the title change from Untitled (100%) - Paint.NET ... to Untitled - Paint.NET .... So that's basically what you suggest. You can also remember to hit Ctrl + D when you paste a screenshot, if you use the Ctrl + V keyboard shortcut, the keys are very close to each-other. Also, I'm sure you'll be glad to hear that the next Paint.NET version is developed and re-factored with performance in mind, even in low-end, single core systems Quote No. Way. I've just seen Bob. And... *poof!*—just like that—he disappears into the mist again. ~Helio Link to comment Share on other sites More sharing options...

mikaelhc Posted February 3, 2009 Author Share Posted February 3, 2009 Minimizing the app doesn't help much - it it easy enough to to deselect the selection (CTRL+D) - but I tend to forget it. The CPU usage is excessive, and I really think it should be fixed - I just tested on my Core2Duo laptop, where I use ~60% CPU. Playing back a DVD movie (fullscreen) actually uses less CPU than animating the border. Quote Link to comment Share on other sites More sharing options...

mikaelhc Posted February 4, 2009 Author Share Posted February 4, 2009 I did read it :shock: - but I am not sure whether some general optimizations would help with this particular issue. On my (old) computer Paint.NET is actually very fast and responsive - that is, except for the display of rectangular selections. Since I couldn't really understand why this should be so CPU intensive, I suspected that it might be some kind of bug, that the developers were not aware of. And, as I wrote, the CPU drain is actually even worse on my newer dual-core laptop. If it will disappear as part of the general optimizations, this is of course good news. I just wanted to make sure the developers were aware of the issue. I could imagine other people being unable to understand why their computer becomes slower, when Paint.NET runs in the background - it certainly took me awhile before I figured out what was going on.

mikaelhc Posted February 5, 2009 Author Share Posted February 5, 2009 That is excellent! I thought the optimization stuff would be part of version 4, so this is even better than I could have hoped for. Quote Link to comment Share on other sites More sharing options...
