NotMyFault Posted April 23, 2021 Share 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 | Windows 10 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 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. My posts focus on technical aspects and leave out most of social grease like „maybe“, „in my opinion“, „I might be wrong“ etc. just add copy/paste all these softeners from this signature to make reading more comfortable for you. Otherwise I’m a fine person which respects you and everyone and wants to be respected. Link to comment Share on other sites More sharing options...
