Affected version: Affinity Design 188.8.131.52 (Windows) and confirmed on 1.6.2 (macOS)
OS: Windows 10 Pro x64 1709 / macOS High Sierra
We have a project file that includes two artboards, where one is always exported with a broken color profile on TIFF (CYMK).
This results in three outcomes, depending on the software used with that file:
- Windows image viewer and thumbnails: partly read color profile resulting in a color tint
- Affinity Designer, Photo and Adobe Photoshop read the file without error and display correctly (probably more tolerant error handling)
- Paint.NET aborts loading with a stream read error on the color profile section
So the TIFF file is clearly damaged or only partly saved.
The project file was started from a copy of a previous project, which exports its slices without issues at same settings.
The new project file with the problem has the same export bug on Affinity Designer for macOS (using latest 1.6.2), so I suspect the file itself is somehow damaged.
I prefer not to share the project file publicly but can provide it to support for debugging purpose of course.
Here is the preview, the the labels are exported slices from the same AD file (two artboards).
The left one is correct, the right one has a red tint.
