1. Add a window to your plot
2. Place some elements on top (with the same or higher Z-value)
3. Click on the window element to select it
Now the elements on top are hidden. Maybe I don’t get it, but I don’t find it very useful. I haven’t experienced this before, and maybe it has been introduced with the new container-feature of the window element.

Hi Ulrich, this behavior is started from V2.62. The reason is that we used a new mechanism to paint the plot (in order to improve rendering performance). All non-selected content will be painted as “background” and the selected content will be painted as “foreground”, this can improve the rendering performance a lot but the elements on top can also be covered by selected content.
You can think that the selected element is temporarily placed on top, and it will be restored when it is unselected. Performance has higher priority so we don’t plan to change this behavior.
Ok. I did not know that.
The problem with this behaviour is that it makes it really hard to adjust the size of the window to fit the content. You need to see the elements in the window to know how wide or high the window has to be.
This might improve perfomance but the consequence is poor usability.

The behavior is really bad for this use case, we will consider a solution for that.
We have solved this problem in V2.653. We found a solution to paint the overlaped elements correctly and does not hurt the rendering performance.
