2022-05-03 16:31:14 Patrick Dunford description 1. Kubuntu 22.04 upgraded from 20.04 2. Gimp 2.10.30 native package. 2a. Also affects Gimp 2.99.x Beta Flatpak from Gimp Project 3. File save operations have been shown to be slower by as much as 10 times compared to the same project on Kubuntu 22.04 and same version of Gimp. A sample project has been created with 200 layers each 4800x7200. When saved with better-but-slower XCF compression the disk file size is around 13 GiB. On the 20.04 system the save time is around 8-15 minutes. On the 22.04 system the save time can be stretched out to several hours. A second project tested with 250 larger layers has a save time on 20.04 of just over an hour, on 22.04 it takes more than 12 hours to save.
