Due to a size limit I wasn't able to attach the test file. Here is a link to my google drive instead: https://drive.google.com/file/d/1NbJnvxC1Dm1MeEndZK0tW-By9e9XJkVi Please use the feature requests category on the krita-artists.org forum for these kinds of issues instead: https://krita-artists.org/c/develop/feature-requests/17 Users can vote for threads there (you can vote for your own thread) and leave feedback more easily than on this developer-focused bugtracker, so the forum gives much better insight in that regard and makes it easier to reach affected users for testing attempted fixes. The bugtracker is really only good for actual bugs, cf. the "reporting bugs" manual page for which kind of issues make sense to report on it: https://docs.krita.org/en/untranslatable_pages/reporting_bugs.html#only-report-bugs |
Created attachment 187089 [details] gif demonstrating the issue Issue: A layer setup using "blur filter masks" slows down Krita severly. It is not excactly a bug, but a heavy limitation in image editing, Test file: 1200 x 900 pix, 16bit integer (attached to this report). Test system: CPU: Intel Core i7 - 10750H (6 cores, 12 threads) Max Turbo Frequency: 5.00 GHz Processor Base Frequency: 2.60 GHz Ram: 16 GB Storage: NVMe SSD GPU: Nvidia RTX 2070 MaxQ + Intel® UHD Graphics Steps to reproduce: - please watch the provided gif The gif animation shows the time it takes to enable the layer groups containing the blur filters. But changing something in the layer stack also is slow. If the blur filters are disabled everything goes faster. Tested on Krita 5.2.13 and Krita 5.3
