I readed many forums, but never found some analogue case.
Javascript canvas font displays in a flickering fashion. The conditions appears to be:
- scale of the canvas is not an integer (for example setScale(0.1,0.3))
- setTransform(1,0,0,1,0,0); and setScale are used widely to restore setting at every draw of new objects.
- Windows. In linux this effect is barely visible (only in some single chars of the text !?).
If the scale is too little (0.5 or less) the effect cannot be seen.
Using save() and restore() seems to have different effect other than setTransform(1,0,0,1,0,0); ans setScale(sx,sy); so i never use them.
