dsp glitches when switching windows / opening subpatchers (redraw queue throttle?)

hi all - i have a patch that's running at about 25% CPU. when i open sub patches (or send "front" message to a thispatcher in a bpatcher). i get short glitches/crackles in the msp stream when the window opens, and then the dsp seems to operate as normal. is there a way to deprioritize window/gpu so that audio is always more important? something like redraw queue throttle in prefs? appreciate your thoughts!
