Inconsistent frame rate with Morphic when stepTime is low and the mouse moves #3819

Closed mdabidullah closed 4 years ago

mdabidullah commented 5 years ago

Hi, I've been trying to animate things with Morphic and have noticed that at higher framerates, inconsistencies start to appear.

A simple example:

Morph subclass: #MovingMorph
    instanceVariableNames: ''
    classVariableNames: ''
    category: 'MovingMorph'

    stepTime
        ^ 20

    step
        self position: self position + (1@1)

When the mouse moves, the movement of the Morph is affected. The effect becomes more pronounced when animating complex drawings. This phenomena is present in Athens and Bloc, and as both of those are rendered on Morphic, I assume the problem is in Morphic.
