Since 9.1 I’ve been having an issue with my chat box, no addons or addons, where it just decides to phase itself out to about 50% transparency pretty much any time I am not using the chat box. No it’s not interactive / noninteractive settings or anything like that. Can’t seem to figure out what’s causing it nor do GMs know. If anyone’s experienced this and if you found a fix I’d love to hear about it, thanks!
Also I don’t use any UI mods or anything. Default blizzard everything. It toggles between transparent and full color when right clicked if that helps!
There are background color and transparency settings built into the chat window’s settings menu. Have you changed the transparency level to full opaque?
