Mouse bug - clicks not registering and deselecting current unit/city

[xeren]

I wish I could give a solid repro on this, but it occurs inconsistently, and I'm not entirely sure what causes it.

Basically the issue is this - I have a unit or city ranged attack selected, I click on an enemy unit or monster or empty hex and... nothing happens. The click simply 'fails'.

There's nothing wrong with the targeting - the cursor is showing the proper tooltip information for whatever hex I'm pointing at, but the click doesn't go through.

A couple theories on what causes it based on what I've seen:

One is that the city and unit 'flags' are obscuring the hex 'above' them. This definitely occurs when you're targeting hexes just above a city, and I think it might be occuring with unit icon flags as well.

Another is that I'm simply selecting/cycling units too quickly and clicking too fast. I know you need to wait for units to finish moving or animations to finish (or skip them) before you can take another action, but when a click fails due to that, I'm usually aware of it. These situations are without any other actions having just occured, and the click still fails.

This is hardly a game breaking bug, but it's really annoying, since it happens quite frequently. It makes the UI feel really unresponsive.

I did some more testing to see if I could narrow down the trigger - I'm not sure if this is related, but it turns out that actions trigger on mouse release, not mouse click.

That is, the action occurs when you let go of the lmb, not when you press it. It's possible to click and drag and release to move, or right click while holding lmb to cancel.

But it is also possible to click and move the mouse slightly while trying to perform an action, and I'm wondering if that might be part of the issue, because the action isn't triggering where I clicked, it's triggering where I released. Maybe I'm clicking and releasing over an invalid target on or near the hex? A unit banner or similar? Or simply releasing back in the units square or something?

Not sure, but figured I'd update.
