ATSynEdit has such debug define
I enabled it to see why editor shows 20-30ms (Form1.OnShow with editor).
a) editor shows 5 (repaint counter) on show. i put breakpoint in
TATSynEdit.DoPaintEx and saw that unneeded paints were from DoOnResize()
before calling Paint(). ok, i added flag FPaintStarted and filtered them.
b) editor still shows 3 (repaint counter) on show. breakpoint shows that
Paint is called 3 times by LCL. I cannot filter these calls at all. Can
you reduce these calls?
