Commen= t # 1 on bug 11150= 6 from Andrew Sheldon 
I should note that it doesn't flicker at all with the modifica=
tion I suggested.
Presumably, LFC is in fact kicking in at 30fps and below, so assuming that's
the case, it's not really LFC in general that is the problem, just LFC when
just below the minimum.=20

One possibility is that LFC is somehow generating frames at a rate above the
maximum refresh rate for framerates above 30 and below the minimum (35), si=
nce
the range is fairly narrow. Maybe it's tripling rather than doubling the
framerate?
