NotMyFault Posted April 23, 2021 Posted April 23, 2021 (edited) Hi, on Windows, with OpenCL active. the gradient map ignores alpha. Until 1.9.2.1035, a gradient map only affected pixels with alpha >0. On a transparent background, nothing changed. Starting with Beta 1.9.4.1048, the gradient map changes all pixels, even where alpha is zero. This is either a bug, or a change of functionality which totally brakes backward compatibility. If you suspect the OpenCL driver: On the same PC, 1.9.2. does not shows this issue, with OpenCL active. 462.31 (as of 2021-04-12) latest available "studio" driver Regards, Timo 1.9.4.1048 beta gradient map.afphoto Edited April 25, 2021 by NotMyFault added GPU driver details IPv6 1 Mac mini M1 A2348 | MBP M3 Windows 11 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 | Dell 27“ 4K iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.
