Sending from a temp account (as waiting the 7 days (though I had likes with my other post in the H6). I won't be able to respond.
Did you happen to set the statics in the code in BB-CP (around line 684)?
In this issue list, where it looks like the OPi has color bits switched in 16 bit mode (uses an older Kernel RGB pin order, and it causes the bit shift). This looks like it was not implemented and 32 bit runs at 100% until it overheats. Just remember that it throttles the cpu at 60c...so that is probably why frame rates drop (a fan may help reduce throttle).
Possible Options I see:
-Improve cooling, as I think the governor is on (check your CPU clock speed during the run to verify)
-Editing the 16 bit code to shift bits between the Red and Blue on only pixels that have changed and send those in the BB-CP code. (This could also be endianness while using a 16 bit value in the 32 bit address)
-Use a Display that interprets bit order differently in 16 bit mode.
