dmstraker Posted August 1, 2021 Share Posted August 1, 2021 Create document with Document/Transparent Background set, and a layer with black and white. Set Blend Ranges, adjust left graph so you can see transparent background checkerboard. Add Gaussian Blur as child layer. Adjust radius. The moment radius goes off zero, the transparent background goes white. This effect does not happen when blur layer is above pixel layer. Example file attached. blend ranges and blur.afphoto Quote Dave Straker Cameras: Sony A7R2, RX100V Computers: Win10: Chillblast i9 Custom + Philips 40in 4K & Benq 23in; Surface Pro 4 i5; iPad Pro 11" Favourite word: Aha.

NotMyFault Posted August 2, 2021 Share Posted August 2, 2021 (edited) I think this might be another symptom of the known bug handling alpha channel with nested layers targeting alpha channel. Did you try on latest beta? Currently traveling with iPad only, there (1.9.2) i cannot reproduce this issue because of the older bug overshadows your issue. Workaround: adding a group to the pixel layer, and applying the blur to the group.

I tried it with 1.10.0.1127 and it's still happening.
