Description Milan Crha 2020-08-05 05:49:07 PDT

Coming from a downstream bug:
https://gitlab.gnome.org/GNOME/evolution/-/issues/1049

When a JPEG image has set an orientation (like `Orientation : Rotate 90 CW`), the image is drawn with a blur left edge. The downstream bug contains both a test image and a screen shot what the WebKitGTK does with it. I can reproduce the same in the MiniBrowser, hence this bug report.

Another user confirmed this with webkit2gtk3-2.28.4-3.fc32.x86_64.

This is quite likely the same as bug #95299 which has a proposed patch
attached to it by Lauro. I have added him in CC, in case he can confirm
it's the same issue.

Yeah, same issue (non-square image, rotated 90/270 degrees, gets left padded and wrongly scaled). Marking as duplicate.
