It seems that because the ribbon cable has both the analog and digital
signals, the analog signals are affected by the digital ones (hence
the touchscreen was working OK when the display was disabled). Putting
decoupling capacitors on X+, X-, Y+, Y- reduces the noise and the
false events disappear.

IOW, the root cause is a design flaw in the BB-View 4.3 Cape?

Thanks,
