From the first SS, you can see there is some weird white empty places at the bottom and at the right but the screen size reports 1000x600, with the second SS it looks more normal but then it reports 1004x632
Ok, thanks. I've seen these weird white empty places before and filed #13142 (moved) for that but was not aware of the resizing this causes after leaving fullscreen mode/minimizing the browser to the taskbar. Duping this over to this one.

The latest TBBs start to shrink their sizes to properly rounded inner window (previously - as in comment:10), but not in Windows XP (STR: minimize and back).
