--- Comment #1 from Hector <misha.bossm...@yandex.ru> --- I have a 2000 x 2000, 8-bit layer. I click on add a layer filter with a gradient map already set. It starts to calculate the default gradient (forground to transparency). In beta2 on Windows, it takes 13.5 seconds to fully update the preview. On a Linux virtual machine 4 sec. After I can draw on a Linux virtual machine and the colors are immediately updated. In 16-bit, on Windows 1 min 15 sec. On Linux virtual machine 30 sec -- You are receiving this mail because: You are watching all bug changes.
