When ever I log in, my chat tabs backgrounds only go to about 50% solid backing/transparency. I cannot get them to go any darker. Yesterday (11/4/22) it was working just fine and I had a solid black background for my chat tab windows. Now? Barely a smoke grey color.
Hello. Do you happen to have Prat3.0 addon installed? If you do you, can change the behavior of the chatframe by going into the addon options under Display Settings|Frames and changing the “Set Chatframe Alpha” to 1. Or just disable the addon completely.
I had the same issue and found this was the case for me.
