Tshik Posted May 25, 2022 Posted May 25, 2022 OS: Windows 11 Affinity photo:1.10.5.1342 Steps to reproduce: Open and image，e.g. https://upload.wikimedia.org/wikipedia/commons/d/d1/Ischnura_senegalensis_August_2008.jpg Filters - Colors - Auto Levels Export images as tiff with TIFF RGB 16-bit preset Some pixels become transparent and results transparent lines on image Other information: Export as 8bits tiff seems not have this issue I can confirm Auto Levels filter causes this issue but other filters is untested. Exporting image without edit seems not have this issue Ischnura_senegalensis_August_2008.tiff Quote
Old Bruce Posted May 25, 2022 Posted May 25, 2022 You could try turning off Hardware Acceleration in the Affinity Photo Preferences, it is the Performance tab. Quote Mac Pro (Late 2013) Mac OS 12.7.6 Affinity Designer 2.6.0 | Affinity Photo 2.6.0 | Affinity Publisher 2.6.0 | Beta versions as they appear. I have never mastered color management, period, so I cannot help with that.
