Summary	0000259: Loading 90+ GoPro images in separate tracks only renders visible tracks.
Description	When loading the images, only those tracks visible in the main window (in my case 5 or 6) are rendered, so if you scroll down it takes quite long for the new tracks in the window have the picture (about 20 seconds for me). Once they are done, scrolling up/down goes quicker, but still you have to wait for it. And CPU load is about 23%, so there is room for improvement. This is an 8 thread CPU. You can notice it stops rendering because CPU load goes to zero. See also issue 258. I see no Settings that I recognize as having an influence.
Steps To Reproduce	See description.
