Could this be something fixable by reducing the speed in the dtoverlay?
Can DMA be configured/disabled through freeplayfbcp.cfg? or would I need to recompile all of them?
I touched on this in the previous reply. fbcp-ili9341 compiles in all its SPI settings (like speed, etc.). It doesn't need the waveshare32b line in the config.txt.
You should be able to use https://github.com/TheFlav/rpi-fbcp and waveshare32b-fp.dtbo. That would be a good exercise/test, but it won't be as fast/optimized as fbcp-ili9341.
If you use fbcp-ili9341, read the INSTALLATION section at https://github.com/juj/fbcp-ili9341
It talks about making sure to REMOVE lines like
dtoverlay=waveshare32b and dtparam=spi=on from your config.txt
