Not a problem here, might be MAC only?...
@Kent Davis (mac4kent) : not sure why you mention "Edit > Preferences on THEME tab"? Are you saying this only happens when you change a color there? If so which one? So this is not a problem with Factory Settings?
(just checking to find the cause of this...)
I just found out recent. Not worry about THEME.
I think so yes Mac but some time have Windows too I guess.
Interface on Resolution Scale
When drag become small text from big text cause appear "J" when become big text from small text cause disappear "J"
I show you on youtube.
When you see my mouse drag please look out on "J" on Object menu you will notice.
@Kent Davis (mac4kent): I've noticed in all your bug reports that you attribute any and all your bugs to be Mac-specific. While there may be issues that only manifest themselves with a certain OS, GPU or driver, most bugs in Blender are not platform-related.
Anyway, this specific case is not a Mac issue, but related to using a very different theme, with things at very different scales.
Generally, there has been a bug throughout 2.8 that causes the first letter of text strings to get wrongly cut off:
So I think this is a bug, but not visible in the specific case posted when using the default theme. The bigger issue is the cutting off of the first letter of text strings in general.
When UI scale is set to 4x here, I see this:
It's even worse!
But a retina scale of 4x is actually equivalent to 8x (!) UI scaling for peasants with low res screens.
Still, it shows the issue well :)
