I have a project that uses Win2D
. If the docking control only has 1 control, if I dock the control a few times (sometimes just on the first dock), then if I increase the size of the control by dragging the edge, any calls to Invalidate Win2D are suppressed, docking control just scales the content to fit the window. This does not happen if I add another control.
I have attached a project to reproduce the problem. In MainPage.xaml
If you uncomment
Then it works as expected.
