Sure, closely inspect the RGB-data from glamo (close at glamo) with a DSO, to 
find this flicker in diff of 2 (3...) frames. (trigger VSYNC) Then it's 
glamo.

Check timing and shape of RGB and PCLK at LCM, using a 18chan DSO (trigger 
glamo side PCLK?). If it's all just rock solid there, it's LCM internal, 
otherwise it's crosstalk etc on glamo->LCM.

my 2 cents
