I created two tabs(tool windows) in a ToolWindowContainer. I painted something in one toolwindow when the window is loaded in the C# code.
Here is the problem: I click the tab of the other window then click back to the window that I painted, the content dispears. But if I drag the window around, rearrange the windows layout, sometime the content can randomly reappear.
Here is the test codeAnd the corresponding c# code
