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!

  • You could try this; be sure to read the comments. In case it's not clear, this means not setting any rotation in config.txt. – goldilocks♦ Oct 25 '15 at 19:29
  • Thanks for your response. I just installed the latest firmware update and it fixed the problem! – James Hunt Oct 25 '15 at 20:17
  • Can you post that as an answer quickly? – goldilocks♦ Oct 25 '15 at 20:19

So seems I basically needed to update the firmware and this was the answer...

  • I updated the GPU firmware using sudo rpi-update but the tearing is still present on display_rotate=3. Did you do anything else? – DrenImeraj Oct 26 '15 at 18:25
  • @goldilocks sorry for bothering you, but James doesn't seem available. I have executed sudo rpi-update and sudo apt-get upgrade but nothing happened. Did I miss anything? – DrenImeraj Oct 30 '15 at 10:41
