Uploaded grayscale image shown distorted

[jaroslavknotek]

Hello, when I upload image and try to open it in the editor then I see image that is distored so much that the point of interests are no longer visible.

Input image(cropped):

Image in the editor:

As a sanity check I performed export to see whether the image is correct and the image is almost identical to the input on (almost because you can set a compression while uploading). Using the current develop version and opening the project in firefox I noticed that there is css attached (link here) that adds filters saturate and contrast. Is that related?

Can you tell me what is going on and how to solve this? Thanks

Update

I noticed that the data is pulled using this route:
/api/jobs/45/data?org=&quality=compressed&type=chunk&index=0. Notice the parameter quality. When I download the data using quality=compressed then the data is absolute junk. When used with quality= then the data 8 times larger but everything is visible.

It turned out that this is still an open issue
