Hello. I just exported PNG image from Paint Net and it looks different in different viewers and editors. And most important - it looks as worst variant in game where I need this image. There is example how it looks on my computer with different editors:
Paint Net, Paint, Microsoft Image Viewer, Browser - (fine):
IrfanView, SnagIt, game - (black artifacts at down and top right):
I tried some online photo editors to resave image but issue with image is still left.
I would appreciate a guide how to make my PNG image looks the same in all editors and in the game.
Images I want to use:
