Hi @LilacTree
Not everyone has a sig line.
The fact you can see most of the sig, but the bottom line is cut off, made me think of your post the other day re larger font size plus zooming to enlarge the entire display.
I think you have your display zoomed so large it's cutting off the bottom of the sig.
In my settings, I've opted to see NO signature lines. Not a glitch.
I'm fine with posters that use the default blank avatar. But default or photo, it throws me for a while when someone puts on a different 'face'. Lol!
