Auto-hidden docking panels will expand to a blank white rectangle

[Alistair M]

By default the UI has 3 hidden docking panels for Weather, Polar Alignment, and Plate Solving.

On my computer, when I hover above their tabs, they expand-out as expected but the panel is just a pure white rectangle, with no content.

In order to see them, I have to click on the tab to keep the blank white panel visible, move the mouse to the upper right where I know the control icon is, wait to see the "auto hide" tooltip, and then click there, which will dock the panel and make it visible.

This can also be reproduced by hiding any of the other panels, e.g. the Image History panel.

Details of environment, in case it helps:

Computer: MS Surface Pro 4 (267 PPI display) OS: Windows 10

A different approach will be applied, as I could not trace down the problem. There will be a toolbar with all possible windows now on the right side of the screen where you can show/hide the panels. Will be included into the next nightly build.
