GoldenWitch Posted December 6, 2014 Share Posted December 6, 2014 (edited) After updating to paint.net version 4.04, when I use the brush, eraser, or pencil tool, there are extreme lag spikes where the cursor continues to move, but does not draw or erase. After the spike is over, what was drawn during the spike suddenly appears. Looking at my CPU usage monitor, there are noticeable spikes in CPU usage while drawing as well. Before updating to 4.04, I have never had issues using this program. I've tried reinstalling already. Any thoughts? (Edit: Upon further inspection, the gradient tool, line tool, shape tool, and moving pixels results in the same issue. ) Here is the information from the diagnostics section.

GoldenWitch Posted December 8, 2014 Author Share Posted December 8, 2014 Bump. After updating to 4.05, the issue still occurs. This is very frustrating. All of my productivity has come to a halt as the program is unusable in this state. Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted December 8, 2014 Share Posted December 8, 2014 What happens if you disable hardware acceleration in the settings? (Gear icon at top right. It'll be the first option.)

GoldenWitch Posted December 8, 2014 Author Share Posted December 8, 2014 Apparently it was the image previews on the taskbar. Disabling that setting fixed the problem. I didn't think that would cause problems, but in retrospect, I should have tried disabling that too when I first looked for a solution.
