PTN3460 Flickering

First of all: A Happy New Year to all of you !

My issue is: ptn3460 Flickering.

We are using a Baytrail Qseven module equipped with the PTN3460 for its LVDS output. A second PTN3460 is installed on our Baseboard to convert 2 eDP channels to an additional LVDS output. Everything works fine on standard TFTs (4:3 / 16:9). 

When driving 1920x540 stretched TFTs, the image flickers randomly in horizontal direction. This happens on both LVDS ports and on different 540 TFTs. On a different Qseven module, using an Analogix DPtoLVDS converter, everything works fine.

Is this a known issue / are there already workarounds?

Thanks in advance for any help / hints!

P.S.: I was trying many different timings within the TFTs parameters already.
