I use a custom watermark (graphic/png) in LR Classic (12.2.1)
Everytime I export pictures with watermark, the first picture is always wrong. The main colour of my watermark is yellow. The very first pics watermark becomes blue, this happens mostly once per LR session, first export of this session. I already tried to deactivae GPU support for export like mentioned in another thread in this community, but this didn't changed the behaviour.
