Weird bug with TRegionTool.DrawBehindSeries

Post by jens.mertelmeyer » Wed Sep 14, 2016 9:59 am

  • IDE: RAD Studio 10.1 Berlin (24.0.22858.6822)
  • TeeChart: 2016.18.160504 32Bit FMX
This took me quite a while to figure out: When the TRegionTool of a TeeChart becomes active and has "DrawBehindSeries = True", then other parts of my form randomly become missing. They're not drawn at all. When they change (for example hovering above it with the mouse), some of them might become visible.

I have attached a sample video, please let me know if you need a sample project.

I am puzzled as how a single component (TeeChart) can mess up the whole form, even at design time.
Please let me know if this is a bug or I am doing something horribly wrong :-)
