I Have strong reason to believe that there is a bug with regards to setting the Background class for the left panel in a VP.
When doing exactly the same settings for Main, or right panel it works perfectly but for the life of me I cannot get the Left panel background to be anything other than white. What is strange is that it was working and then suddenly stopped!! I Restarted my Computer, reverted to an earlier BSV... nothing worked.
See images below:
Please advise if you are ware of this and weather this has specifically been fixed in 5.9?
Kind Regards
Hein
