Rendering issue UserControl in VSTO TaskPane

Hi,

there appears a white vertical line in the TaskPane area one pixel to the left of the left border of a standard UserControl. To reproduce the error you need to open a MS standard task pane (e.g. "Format shape") and a custom TaskPane.

This appears irrespective of DPI settings or initial width of the control. Make sure to use the "colorful", "dark gray" or "black" office theme to see the rendering error.

The error does not occur when opening e.g. two custom TaskPanes - it only appears if a standard MS TaskPane is opened.

Any idea how to fix this?

Thanks!
