So it's happening on the 32bit version of the game, but not on the 64bit version? That's very strange and would certainly be engine related unfortunately. This update does include an engine update, so all I can suggest is giving it a go. I'm not aware of any specific issue like that being addressed but the Ren'Py changelogs tend to skim over a lot of stuff. Worst case, just use the 32bit version - there's no harm in doing so.
