[BUG] Vulkan samples GPU hang (quick window resize)

[Dorian]

Hi,

There seems to be a problem in CapsViewer demos, when you grab window by frame and quickly make it smaller/larger.

GPU Caps View Version 1.58.0.1
Gfx: Intel Arc A770

It looks like demos can render outside of render area/framebuffer, which is forbidden by Vulkan spec:
"The application must ensure (using scissor if necessary) that all rendering is contained within the render area"

Scissors/viewport should be adjusted in time to match frameBuffer/attachment size.
