Christian,

I just wanted to let you know that we are aware of the bug. The mouse gesture text shouldn't be pickup up its color from the UI background setting. Unfortunately, I don't have a fix target release to announce. But please do know we are are aware that it needs to be fixed.

Christian,

I now have target release info for the fix to Mouse Gesture text for you... this is fixed in SOLIDWORKS 2017 Beta 3 (available mid-August) as well as SOLIDWORKS 2016 SP05 (early visibility mid-September, available mid-October).

I have seen the fix in our development builds, and the Mouse Gesture text is now identical to what it was in SOLIDWORKS 2015 (and earlier) regardless of the background setting.
