I'm trying to set the rotation on the Raspberry Pi to portrait mode. On startup the RPi GUI is shown looking fine but if I move anything (a window for example) then the screen tears (not fully repainting the background). I was wondering if this is connected to the monitor HDMI settings and I have tried several different options all to no avail. I followed the WHICH VALUES ARE VALID FOR MY MONITOR? instructions and the results are below. I also have the edid.dat
file if anyone would find that useful.
I'm really stumped how to stop the screen tearing like this - needless to say this only happens when display_rotate
are set to 1
or 3
.
Any ideas would be very welcome!
