I've worked on several applications where I've had images be drawn on
a canvas in which, in the windows build, the canvas 'flashes' briefly
when the images changes. This is distracting and incorrect behavior,
but I've never been able to eliminate it. I've recently been working
on a simple application that suffers from the same problem. If I
recall correctly, suggestions for fixing this have been to build the
image in a picture off canvas and display it all at once. Doing this
doesn't help.
My impression is that the problem is an interaction between canvas
drawing and the screen refresh rate of the display, but that is a
guess. The problem is irregular in that, if I make a picture display
on a canvas when I click on the canvas, the flash (or flicker)
doesn't occur with every click and isn't always identical.
Again, any suggestions are appreciated.
This seems like something that REALbasic should be fixing.
