What's wrong with this ctrl?

Transparency + overlapping objects can lead to a situation with constant redrawing.  In this case (LV14 SP1) I was able to tame it by coloring the housing a solid color and then recoloring it transparent.

Good catch using Spy++ in the first place.  Not sure I would check every control, but I have always found gauges and meters to be particularly troublesome, so I would check those.  If you ever color a part transparent I would think about checking, but LV has gotten much better in the past decade.  Once upon a time I actually used the fact that an overlapped, transparent picture control triggered excessive redraws to "fix" problems with controls which were glitchy from a lack of refreshing.

Was this control born in LV14 or was it upgraded from an earlier version?

I added this gauge to an existing VI/proj. in LabVIEW 2014 SP1, and then customized it.

The VI/proj. was upgraded from LabVIEW 2011 previously.

Had a huge performance problem with a translucent button before, so I checked when I have performance issue again.
