Forum images are high-contrast

By uploading (usually a screenshot) any image to the forum, the result should be a high-contrast image that does tire the eye and it’s not compatible with any tiny text.
An example can be viewed in this topic reply.

The issue seems to be present on the desktop, web version of the forum. The mobile PWA app loads the image correctly.

Expected behavior:
I expect the images to not appear different than the one I have on my computer (except for quality-loss).

Actual Behavior:
Images appear to increase/decrease their contrast value, making them appear distorted.


If you click on the image to enlarge it on desktop, does that show the image correctly (this loads the higher-res image).


No, the image still remains the same even if I click on it.
