*** SUMMARY Starting a certain build version, Krita 5.3.0 prealpha and now Krita 5.3.0's first beta, is running with a UI extremely slow in almost all places. The only place that is seemingly not affected is the scratchpad. STEPS TO REPRODUCE 1. Open a document and create multiple layers, at least 3 or 4 2. highlight one layer or the other with the mouse left click 3. on the canvas, attempt to rapidly make fast strokes with a simple brush. The basic opacity or ink brush is fine OBSERVED RESULT Stutter, delays, or lags with all the operations described above. Major freeze with the rapid strokes on the canvas. Oddly enough, the scratchpad isn't affected by the lag and stutters/delays. EXPECTED RESULT No stutter or lag on the UI or the canvas. SOFTWARE/OS VERSIONS Windows 10 Pro ADDITIONAL INFORMATION CPU : Core-i7 3rd gen mobile GPU : Nvidia GT640 M
Can you identify which build it started at? (Or the last build that did not have this problem)
