Hi list,
I'm writing a little charting morph, and while playing with rotating text for axis labels came across something which I've noted in Morphs text handling a couple of times.
If I apply a transform in a drawing operation, rotated text _appears_ to be drawn twice, slightly offset, giving a scrappy bold look. It seems only to do this when drawing on a form canvas that's backed onto the display: if you pick and drag the morph, the text is rendered beautifully.
The test morph attached isolates the problem. The transcript logging is an attempt to see what might be happening: looking at the output it appears that there are circumstances in which the during: block is invoked twice.
Any thoughts?
David
