Mineshot Screenshot Problem

[Daosis]

So, i installed the Mod for 1.8 with Forge
Then i pressed F9 to take a huge screenshot, but...
After i opened the .tga file with picasa (only program i managed to find wich opens such huge files)
there was just 1/10 of the screenshot?!?

Could someone help me solve the problem, or is it a bug from the mod itself?

I guess the framebuffer texture wasn't resized correctly for some reason. Does it work with tiled rendering? Also, can you spot any warnings or errors in your Forge log files?

Optifine's fault. You have to turn fast render off.

For those of you wondering that stumbled across this, you must also disable Antialiasing for Mineshot to work correctly with Optifine.
