Hi all,

I have brought one of the new 7 inch Pi touch screens. I have the Pi booting straight to the LXDE desktop. When it is finished booting there is an annoying black rectangle in the top left corner of the screen.

Done a lot off searching on line and in the forum but have not been able to find a solution.
Has anyone else had this problem and or a solution?

Hello,

When my screen was freezing I always had this black rectangle at the same place.
But it was only when it was freezing...

Try to update your firmware, it fixed my freeze issue, so maybe it will fix your issue too

I've just upgraded the firmware using rpi-update. Everything went well, no errors but after rebooting I still have the small black rectangle :(

Okay, I don't know if I've found the problem, but it may be from using a custom splash screen.
From another post I have found the following work around:
Find the file that is running the fbi command. In may case it is /etc/init.d/asplashscreen
Find the line "/usr/bin/fbi -T 1 -noverbose -a /etc/splash.png" and change the "-T 1" to "-T 2".
Save and reboot.
Credit for this fix to "anigel".
