Some images are bugged on Opera Developer
I am using Opera Developer version 47.0.2615.0 on Xubuntu 16.04.2 LTS (x86_64; XFCE). A few images which I see on the navigator appears with very strange colors. This bug appeared since I updated to the last version of Opera Developer and this isn't happening with Opera Stable.
An example of a problematic image is at https://cdn.arstechnica.net/wp-content/uploads/2017/04/IMG_4055-1.jpg
To give an idea of the difference, I have downloaded the image and opened with the program eom (Eye of Mate). The left image is opened on Opera Developer, the right one is opened on Eye of Mate:
I believe there may be a problem with Opera Developer path, as it can be seen on terminal:
$ ldd $(which opera-developer) | grep "not found"
libffmpeg.so => not found
However, when searching:
$ locate libffmpeg.so
So the libffmpeg.so is installed, but it is not on Opera's path. I am not sure this alone would solve, but this may be causing problems.
While most the images load correctly, it's strange that some of them have problems. As this happens on Developer but not on Stable, if the problem is corrected before this version reaches the stable version, the stable users will never see this problem.
