White screen

Hi everybody,

One week ago, I've bought a new computer (because my old one doesn't function anymore, I need to tell it because this pc is worse than the old one, I mean less memory, worse graphic card, etc.)

I had a backup of my configurations, so I've just set them and started my client (my own one), I never play teeworlds full-screened (to see if there is any skype notification, and such things).

I use alt + tab to switch pages, and sometimes I click on the bottom right part of my screen, to minimize all the pages.

So when I do that, the client gets white. I've done some tests, like deleting the configurations, changing the client to take the official one, but no, nothing, it keeps being white when I click on the bottom right part, to minimize all the pages.

I took a screenshot to show you what does it do exactly (and no, there is nothing to do when this happens, except closing the client, for sure, if I'm mapping the map won't be saved, no configuration saves, etc, I mean just that I have to close it with a right-click and close.)

NB : I've done all the driver updates, nothing changed.
