VNC painfully slow

[PaddyB]

It worked fine before!! 

Now using realvnc viewer opencpn & chromium are unusable, can't work out what has changed. 
With mesa utils..
glxinfo | grep -i "OpenGL renderer"
gives > OpenGL renderer string: V3D 7.1
But framerate is about 1 per sec

Running synchronized to the vertical refresh.  The framerate should be

approximately the same as the monitor refresh rate.

313 frames in 5.6 seconds = 55.568 FPS

5 frames in 5.0 seconds =  1.000 FPS

6 frames in 6.0 seconds =  1.000 FPS

6 frames in 6.0 seconds =  1.000 FPS

Android tablet also the same and same with a new burn of the latest OPv4 image. 

Is it just me??

Think we're all sorted again >

#### install.
- sudo apt install tigervnc-standalone-server
- tigervncpasswd ~/.vnc/passwd
-  tigervncserver :1 -geometry 1280x720 -depth 24 -localhost no

Realvnc viewer seems to work OK on android, also on win11 though the tiger viewer seems a bit nice looking. And i don't like realvnc now
