Attach your EFI to check!

I am having the same problem with 1.0.3. I moved back to 1.0.2 and graphics worked perfect again. I used OCAuxiliaryTools to switch between versions (including updating *.efi driver files). Everything looks perfect but still - as soon as I switch to 1.0.3 the boot picker disables graphics and goes to text mode)
Looks like a bug to me. I will stay in 1.0.2 until it is fixed.

Umm, that's weird. Running v1.0.3 as well and can see the picker. Attach your 1.0.3 EFI to check further!

Found this post: https://www.insanelymac.com/forum/topic/360338-how-to-opencore-102-103-differences/ and changed Misc/PickerAttributes from 255 to 145 and now GFX Picker works fine with 1.0.3.

Umm, how about PickerAttributes set to 17?

Yes, This basically works. But then the "default" icons are used (bit 7 = OC_ATTR_USE_FLAVOUR_ICON disabled) which is fine but I prefer to use more colourfull icons (triple boot linux, windows, mac - I see the boot picker quite often ;-)
I just checked - even a zero or one for Picker Attributes works if you don't need mouse support and/or individual volume icons.
In the end I found out that the only setting that prevents graphics is bit 2 (0x04) = OC_ATTR_USE_GENERIC_LABEL_IMAGE. You can set any combination from 0 to 251 - as long as you leave OC_ATTR_USE_GENERIC_LABEL_IMAGE disabled you get graphical boot picker.

Sounds great!

Been a while and haven't used custom icons, other than the default one. xD
