Window contents wraps around when the window is resized and its contents does not fit
I noticed a strange behaviour on window resize (screenshot attached).
For example, when the vlaunch window is resized so that the HelenOS logo does not entirely fit inside, a couple of the pixels that no longer fit (on the right) wrap around and are displayed on the left, before the first pixels of the logo.
Another example is how the buttons look when the window is resized so that they no longer entirely fit inside. In that case, the buttons are displayed at the expense of the window border.
