I got the "unreadable" situation when i don't apply "forced" with scalers.
So best use
forced scaling.
If this doesn't work then it's a Wine issue, can't help here, because it works as intended in Daum under Windows.
Don't forget to customize the #define values to your liking though...
Enough OT for now.
You can send me a pm if you need any more help/ot shader.
