Graphic bug in some of v6's native Rea... plugins

[akademie]

There is a visual graphic bug in some native Rea... FX plugins in Reaper v6.x
(specifically: ReaEQ, ReaDelay, ReaXcomp, ReaPitch).
Those white places under almost all labels and framing tabbed sections.
(test environment: Windows 7 Pro 32bit, Reaper v6.05, v6.04 all down through to 6.0, and v5.70, all 32bit)

It used to be all white in 5.70 etc.

Here are screenshots of buggy graphic plugins in v6:





Here are screenshots of not-buggy graphic plugins in v6:



And here is a screenshot of graphic of the same plugin (ReaEQ here) in v5.70:
