OpenGl problems.
If you make  an application using two forms where use opengl canvas and a timer to update data, the labels of axes were missing when you close the second form from first form. To reproduce the problem you need open/close the form more of twice. The problem only occurs in Activex and in vcl it works fine. 
I have attached 2 projects one write in VB6 and the other in VCL to reproduce the problem.

It isn’t a bug. To solve the problem is necessary repaint the labels, always, when you close the auxiliary forms that depend to the base form. Therefore, should be used the Environment.InternalRepaint method to prevent the issue. The lines code below shows how: 

Private Sub Command3_Click()
Unload Form2
TChart1.Environment.InternalRepaint
End Sub
