That could be the case but you are not the first who reported a similiar problem. I would love to fix it but since I can't replicate it I have a hard time figuring out what the problem might be. I know that rpg maker games sometimes have a problem to run on specific graphic cards or very new system but the bugs produced by those are usually way more noticeable and also game breaking.
And no worries, you're welcome! I'm sorry that something like this is ruin the fun for you-_-
