Fixes minimization crash because of cluster updates. (#3369)

Browse source 
# Objective
Fixes: #3368

Issue was caused by screen size being: `(0, 0)`.

## Solution
Don't update clusters if the screen size is zero. A better solution might be to not render when minimized, but this works in the meantime.
