Done de latest kernel upgrade to 4.9.57. Switched on the VC3 accelerated driver en OpenGL in OpenCPN to on.
Accelerated video with OpenGL now works with a low processor load. Don't switch texture caching to on.
Now the screen movements are fast and Linux Stretch (Debian 9) is very stable. Only the upgrading of OpenPlotter does
not work. And I had to install Egalax touchscreen driver with some adjustments. Do the upgrades in Jessie first before upgrading to Stretch.
All the OpenPlotter items and oeSenc plugin stays working.
