Oh... well... I got reports of EXACTLY the opposite, having a little lag after each click while text is appearing , but animations and scenes working fine right after it finishes...
Now I'm even more confused.
I think I just suck at explaining what's going on.
So like, panels appearing? Fade in fade out sorta animations? Text scrolling? No lag. But randomly, when any of these is done, the program just says "yea well im out now" and you cannot click anything. Like at all. Not the menu, not the next scene, none of the buttons, happens in the menu, save screen, while in the game, doesn't matter.
So while it's actively playing a scene, animation, or text, there is no issue, but as soon as it finishes there's a decent chance it will just freeze up. Sometimes it's fine for 4-5 lines of dialogue before freezing up like hell again. Generally, I can only play 1-2 lines before a freeze. Freezes tend to last 20-30 seconds. Hope it helps.
I uninstalled and ran 2.4 again and it was working without issues.
