graphics32-1-9-1-r1574 tested
in image view layers example:
create simple drawing layer (spiral), resize it and move it
does not work together with "optimize repaints",
the curve is gridlike teared.
Error due to PUREPASCAL implementation of function MulDiv(Multiplicand, Multiplier, Divisor: Integer): Integer; which can be found in GR32_Math.pas
For now a slower replacement is used that does not show the issue.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Can you provide further information? What compiler are you using, etc.
Also a screenshot would be helpful to see, what you mean with 'gridlike teared'.
Optimizer issue
Only present with PUREPASCAL enabled!
