Do you remember if this problem started after updating wme?
Also, can you please upload a jpg & a png that has this problem.
Thanks for the reply Odnorf!
Alas, stupid me doesn't remember if it started after an update... though my WME is up to date.
By the way, this behaviour changes, for example: a project where the scene's background looks ok in the ProjectMan, but distorted when the game runs.
Here is a problematic jpg:
that appears like this in my SceneEdit:
and like this when the game is run (sometimes worse!):
Thank you very much!
