Only in XBMC - resolution on boot is native 1920x1080.

Just testing r12014 and it's the same, XBMC comes up as 640x480 (been testing OE for ages now, this resolution problem is only a recent issue).

Delete guisettings.xml and tell me what happens. No need to tell us the build number, we got it that this happens with recent releases.

I'm booting a fresh image - there is no guisettings.xml when it boots, just an empty ext4 partition.

FYI, my config.txt:

Code:

config_hdmi_boost=7
disable_overscan=1

So I'm not specifying any HDMI settings, other than overscan and boost to try and stop the HDMI from blanking periodically (doesn't stop it, unfortunately).

I'm currently trying to pin down SD corruption issues due to overclocking, hence why I'm testing with fresh images each time...

Your overclocking settings are to high when you see image crruptions. Go back to the normal clock settings and remove config_hdmi_boost/disable_overscan from config.txt to see if the problem is related to those settings.
