Imagetrail [faux motion blur] effect that won't quit

[Sexbad]

Hello, friends.

I got through Omicron (I think? Definitely the complex after Theta) yesterday. The effect doesn't bother me, but for some reason I was left with an Imagetrail blur effect that can't be turned off. At first I thought it was a questionable design decision related to the paranormal stuff going on, but it kept going even after

Spoiler below!

I switched bodies and went down to the abyss,

so I think there was an error in scripting.

I can't find any settings in the "My Games" folder that would seem to let me turn off the effect. As I recall, it was optional (and called Imagetrail) in Amnesia, so I was hoping there would be some kind of toggle.

I am using the GOG Windows version, which doesn't appear to have any patches available except for Mac. In case this is relevant, I am including my system specifications and my hpl.log file.

Windows 7 64-bit
AMD Radeon HD7870, 2GB
16GB RAM
ASUS Xonar Essence STX
AMD FX 8320, 8-core, 3.50GHz

Also, two other bug notes that you may want to know about, but aren't big or anything:

Spoiler below!

The first time that little robot unsealed an airlock door for me, I went inside and shut it. Then, the robot squeezed through to the inside and actually unsealed it again. Simon thanked him both times.

The same time that I entered Omicron, my FOV lowered along with the Imagetrail effect. Fortunately, the FOV went back to normal eventually. I was going to fiddle with the FOV settings, but it actually reset to my setting the moment I opened the graphics menu.

Thanks.
