I just remembered that at one point I had trouble with Ren'py framerate performance with transforms running over images. Try adding this to your screens.rpy under screen preferences.
It would make the preference section look like this:
If your project is automatically in Performance mode try changing it to off and seeing if that gets rid of the lag, to force it to always off add this somewhere in the project.
Code:
vbox:
style_prefix "check"
label _("Performance Mode")
textbutton _("On") action Preference("gl powersave", True)
textbutton _("Off") action Preference("gl powersave", False)
textbutton _("Automatic") action Preference("gl powersave", "auto")
Code:
