It only happens in the main part of Cyseal - the area with the merchants and buildings - and it happens every time as soon as I enter the area, usually for a few seconds at first, then when I walk further in, it happens a few more times for longer and longer periods then just goes on forever until I quit and reload, which fixes it for about a minute before it starts again. I haven't had it happen in the docks, on the beach, or in the tutorial dungeon.

When it happens in a dialogue screen, it doesn't seem to matter if the characters are moving or not. Even if they're all standing still when I start dialogue, they'll start walking away in the middle of it and I won't be able to select anything.

I did notice something else when testing it just now, it's not just my follower that starts walking away when it happens, NPCs are too; I saw them start walking out through the tavern walls.

I'm not running any background programs, tried it again with antivirus disabled and it still happened. Also, I'm just using the regular GOG installer, not Galaxy.

I'll see about sending that report, thanks.
