As far as I know, this is still an issue, and probably even more so now that 60 fps is the generally the minimum framerate for a modern display and many support 120fps+.
I believe the JUCE team is working on fixing the root cause of it rather than adding an option to turn off the throttling or making minimumRepaintInterval configurable (as @t0m alluded to here: Is the JUCE team still here? - #2 by t0m)
One way around it at the moment is to use the OpenGL renderer, but that comes with its own set of issues/complications.
