A DESCRIPTION OF THE PROBLEM :
Application crashes (with -Dprism.maxvram=300M and -Dprism.pooldebug=true)

see provided code

While `Canvas` object is recreated every time it is toggled on it consumes much more VRAM, than if it's created on object creation.
And it appears it doesn't break under this condition.

It doesn't break also when we create canvas on button "click", but we comment out `gc.clip()` and it consumes much VRAM, but it's freed correctly.
If we doesn't comment out `gc.clip()` it breaks, it consumes much VRAM and doesn't free it correctly.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
fire up the apps on a larger-than-laptop display and wait up to 2/5 minutes

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Application doesn't crash.
ACTUAL -
Application crashes with logs provided in description.
