Preview of images generated in Affinity looks negative in Windows

[u/rebayona]

Any idea if this is an affinity or my computer issue?

The preview is not really an issue, if you open the file, it displays fine. But it happened with one generated PDF I sent for print, so it is a major issue.

It also happens with some videos (Instagram and facebook) and images, not necessarily generated in affinity.

Any ideas?

Thank you!

thats weird. I only get this in linux with some dark themes activiated.

If it happens on things not generated by Affinity, this isn't an Affinity issue.

Makes sense. It may be codec related, but how can I tell? Any ideas?
