More testing... I think the problem here is not the speed at which i can splash stuff onto a canvas (the difference between GTk1 vs GTk2 is very little), but rather the rate at which the OnPaint events are called with the TCustomControl class when using with GTk2
There seems to be a delay of at least 16ms between paint events (i measured 18.519ms). I think the problem might be an indefinite sleep between each fetch from the event queue, or, the fetch is on a timer and only one event is fetched on each timer interval instead of flushing the entire queue on each timer event. I don't know how the GTK2 implementation in fpc works. I'm only guessing here. My FPC version is 2.2.4, target Linux for i386 I have not tried Qt yet. Anyone with more advice?
