Hello all - I'm another newbie with the same problem.
RPi 4B, 4GB, Moitessier HAT.
Pan and zoom painfully slow with oeSENC vector charts.
I've set the GPU memory to 512, which, as the OP said, helped a bit.
I've turned on Open GL in the openCPN settings, but not sure if I also need to turn it on in the PI settings.
If I do, maybe someone could let me know how to do it.
I'm wondering about the dtoverlay=vc4-fkms-v3d setting. Is this not for 3D graphics?
All help gratefully received...
