Is there any function to check if all the draw tasks are finished?
I know that whenever a (joined) area is drawn, the callback will be called.
If there are multiple joined areas, will the current mechanism wait for all areas being redrawn and called the flush callback “once”? (Based on the document, I think no.)
I need to wait for all the draw tasks finished before I render them to my device.
Any suggestions are appreciated.
Many thanks for your help.
