Significant Lag After SMC Reset - 2015 MBP, Sonoma 14.4.1

Hi y'all! My 2015 MBP has been running Sonoma via OCLP perfectly fine for the past few months. Yesterday, my charger overheated and I foolishly took some advice online to do an SMC reset. Now, my laptop is lagging significantly – like the framerate is slightly off or something (I know it's probably not that, just what it looks like); the dock/system dialogues move slowly and jerkily, video plays back slightly stuttering, etc. The dock also looks weird, like there's black borders around it.

Is there an easy way to fix this? I don't wanna mess it up more. :( Any advice welcome!
