It's likely your client being wonky. E.g. video card, OS version, stuff like that.
emulator version would be more like, messed up loading spellfiles (and can't cast spells at all), or map files aren't there (can't cast spells)
but if you're casting spells ,but having a visual glitch of watchin gthe pretty graphics, that sounds client to me, especially if it's some times happening.
