NotMyFault Posted March 14, 2021 Posted March 14, 2021 Hi, a found a rendering issue i assume a bug. To see the issue, please uncheck the 3 top layers in the stack, and then toggle layer 3 (merged after de-bayer) In the lower area, the merge shows relevant differences (the layer 2 "mark area" can be activated to frame the impacted region). The issue occurs while export, too (with top 3 layers de-activated). Layer 1 is a PNG file showing the result of export (with "merge visible" in-active while export). If you are asking what this composition trys to achive: use a test picture (from wikimedia) apply a PT filter to convert pixels into R/G/G/B bayer filter merged the result and put it into a new file as bottom layer used perspective live filter to downsample R/G/G/B pattern into a new region with 1/2 resolution. I did not find a better way, tried pixelate (destructive), custom blur (bad results) when using different zoom levels at that stage (everything above de-bayer downsample deactivated), Photo gives horrible artefacts. So i tried to merge visible, but this results in a 56 pixel high area on bottom. 1.9.2.1005_merge_visible_issue.afphoto 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.
