I just upgraded a mac project from 1.28 to 1.38. That was pretty smooth, but drawing performance has signifigantly degraded.
When I profile the 1.28 version, the most expensive call is to juce::MacBitmapImage::blitToWindow(), which amounts to 10.6% of my time.
When I profile the 1.38 code, there are three related ColorSync calls that total just over 33% of my time:
I assume these calls are appearing as a result of the 1.35 change to draw everything into HIViews instead of straight to the window.
It looks like a lot of time is being spent to convert my Bitmap colors to match the machine’s colorworld (all three calls are initially called up by img_colormatch_read())
Has anyone else seen this? Is there a way I can speed up this bottleneck on the Mac?
