Process com.android.systemui has stopped responding. Why?

A

AC Question

I have had my HTC Desire 610 for slightly less than a year, and it has always been great. Recently, I've been having issues with the system giving me an error message that says "Process com.android.systemui has stopped responding" and gives me the option to wait, or close the process. Closing the process fixes the issue, but the phone goes dark for about 30 seconds to a minute, and then it's like nothing happened.

The weird thing is, this issue started out of nowhere. I rooted my phone using TWRP, but the issue showed up a month afterwards. I've noticed that I only usually see the issue when using Chrome, and when running the game Smashy Road: Wanted.

Any ideas on what is causing this? If software version matters, I can provide that.
