Interesting thought, I tried it but no luck. Also found I had that ‘lock window when pinned’ setting on. Can’t really see any material difference in behavior with it enabled or not.
From my admittedly limited reading on the subject, I don’t think it actually does anything anymore aside from preventing you from reordering your tabs. I’d read somewhere in the forums that at one time it’s purpose was to prevent windows from being moved when pinned, but I can move windows whether they’re pinned or not even with it enabled.
Settings for each window are saved and persist for me either way - except when logging in, having to toggle pinned and back to unpinned to get the window opaque again. This behavior really looks like a bug in the UI to me. It wasn’t happening at all, then I think I made a new character while playing around and ever since then it happens about 70% of the time when I log in.
Maybe I’ll try deleting all my settings files and starting from scratch. Thanks again for trying to help, and if you have known working settings for 100% opacity I’m all ears. I play on a big screen TV from my couch and transparency is pretty much a non-starter for reading anything at my age -.-
