ToME: the Tales of Maj'Eyal

Hey, this is my first time posting here to te4 forums, so I figured I'd make my first post a contribution.

My graphics card seems to have taken offense to the ability "Flame of Urh'Rok", specifically when shaders have been activated: http://imgur.com/a/uGUfH (45%-95% of the animation is that brown-ish red square, depending on what mood the game happens on to be in)

Radeon's handy-dandy copy-paste function:

Graphics Chipset - AMD Radeon HD 8400
Memory Size - 512 MB
Memory Type - DDR3
Core Clock - 600 MHz
Windows Version - Windows 10
System Memory - 4 GB
CPU Type - AMD A6-5200 APU with Radeon(TM) HD Graphics

If you guys require any more info, I would be happy to oblige if I can.

I get the same thing, except the block only covers half the character. It doesn't look good at all. I've only ever seen how it's supposed to look in screenshots and footage.

Turning off opengl changes the block to an aura of coloured orbs, but that still isn't how it is supposed to look. And, honestly, I don't want to turn off opengl. There are too many good effects that I would lose just to fix one bad effect.
But you just can't play a Doombringer or Demonologist without having Flame of Urh'Rok on pretty much all the time. And you don't want to play a whole run with half your character obscured by a graphics glitch.

Looks like this problem has existed for at least 6 months.
