[Duplicate] White square

[Horance]

Hello,

I've noticed a white square regularly appearing on the upper left
on the screen when selecting units.

It seems to appear randomly when I right-click to select an unit.

Please take a look to the attached screenshot.

Thank you for the report and screenshot.

This one is on the list, it will be looked at ASAP.

I also observe this regulary.

This is hard to lock down as it just happens and isn't always repeatable - it looks like it is drawing a lasso box from (0,0) to where you click with the mouse, but where/how it is anchoring to the (0,0) is a bit of a mystery.
Most of the time it has actually happened to me, has been just after a scenario load when I click on the map for the first time, but not every time.[&:]
