Through both methods of opening the syntax menu, (gutter-right link and view > syntax) I have the panel appear as usual with the up arrow dimmed and down arrow active as per usual.
The problem - text is invisible.
Not sure whether it is text rendering as same colour as background, text not displaying at all, or text caught behind the background panel layer.
I cannot select the text to highlight. Hovering does show the usual pop-up submenu options, and a very slow means of changing syntax.

Have tried changing the colour scheme, as well as toggling through the 2 Sodas and default theme to no avail.

The only changes made beforehand that I can think of to affect the menu is the changing of the system’s overall colour scheme.
Does ST2 inherit menu styles/colours etc from the OS?
