[Alexander Zvegintsev]

> Looks like the test does not fail anymore.
> 
> However some cleanup was made:
> 
> - fixed wildcard imports
> - frame centered and explicitly disposed at the end
> - removed unused `setAutoDelay()` call (no key/mouse key events generated)
> - improved variable naming
> 
> Testing still green.
