Try this in LV8.2:
Create a new vi, drop a tab control on the front panel, and then drop a control (numeric, boolean, not sure it matters), and then highlight the label text. Go to the top bar and click on the font drop down box, and then change the colour of the text. A small 'window' of different colour appears afterwards. Scrolling makes it go away.
I have produced other strange behaviour when setting the colours in my tab control, but have not been able to reproduce them. If/when I can, I will post those also.
While this is not really a big deal, it's still sort've annoying to have to scroll when I change the text colour of something in my tab control in order to see it properly.
EDIT: I just found this with a control NOT in a tab control. Previously I had not seen this... Not sure why I am now.
Here's an example
