Dai-2-Ji Super Robot Taisen Z

Hello there :3
I noticed a very weird glitch during certain attack animations and animation transitions.
As you can see, there's a distortion glitch to the right.
Is there any way to fix it except switching to non-buffered mode, which will disable post-processing entirely? Switching to non-buffered rendering will make bugged frames black as the issue seems to be exactly related to post-processing.
Thanks :3

Using version 0.9.8-950.

Update:
This doesn't happen on version 0.9.6, but mentioned version also has bilinear filtering problems. So I get to pick lesser of two evils, I suppose.
