HOW TO FIX: "GlGetError 0x505" in Raspberry

FIX: In case you enabled OpenGL experimental driver (raspi-config, which works ONLY on raspbian desktop NOT Retropie) and then disable you might get a flashing ES theme and if you press F4 you will see

GlGetError 0x505

To fix this: if not already in terminal/cli press F4. type

sudo raspi-config

and press enter Go to advanced and select the memory split option. You might notice that is at 64MB. Type 256 (or 384 which is a great split). Click OK and go back and exit to cli again Type

sudo reboot

End keep VRAM in ES at 90MB. Dont exceed 100MB!

No your ES will boot fine and display the theme correctly! 2Play!
