Just had an issue with the latest version of OpenCPN 5.6.0.
When I would open OpenCPN it would work for a few seconds and then slow down so much it effectively froze.
After a little messing around it appears that OpenCPN does not handle the Signal K data from OP. With just the GPS SignalK data only it overwhelmed OpenCPN.
I went in and disabled SignalK in OpenCPN and added the gps by NMEA0183 and all was well.
This happened on two different devices with different hardware.
