Summary0003536: Sketcher Issue while using Windows high constrast mode
DescriptionWhen in Windows High Contrast mode, the sketcher doesn't work as expected. When trying on a sketch, items are not visible until you either exist the sketcher or select an already existing line.

When selecting a sketch line, it is not highlighting correctly.

I have tried selecting different stylesheets, but the issue persists.

These issues go away when Windows is not in high contrast mode.
Steps To Reproduce- Place Windows into High Contrast mode. (left-alt + left-shift + PrintScreen).
- Create a new sketch
- Draw line / rectange

@Stonehenge81 Can you recreate with 0.18dev ?
Also please open a forum thread and link this ticket to it (+ add the thread URL to this ticket)

I downloaded the latest .18dev and I still experience the same issue.

After further investigation, I noticed that the sketch (not freecad application) is unresponsive. The same unresponsiveness can be noticed when in the viewing plan. Trying to zoom in / out or rotate is extremely sluggish.

Also, this issue, happening on an Intel system, does not happen on another computer, which is an AMD system. I'm not sure if there is any correlation, but thought I would mention it.

Of course, sorry for the very delayed initial reply. Also, I posted my issues on the Forum. I'll add the link once it has been approved.
