Hello. First, I just want to say that this is a great, minimalistic addon. I am absolutely loving it!

My issue is with the quest log. I can't see any settings in SUI that specifically address the Quest Log; however, right after I installed SUI, I noticed that it was visually glitched. As you can see from the screenshot, the text background spills beyond the border of the window, and there's a dark rectangle in the upper-left side.

I am on WoW Classic, Season of Discovery. Thank you!

outdated and not supported atm.
