[Google Pixel 2 XL ROMs, Kernels, Recoveries, & Oth] sharkie405:
I was good on the new Feb version for about half a day, then I started have SystemUI force closes all the time. I think it didn't start until I started messing around with various Colt settings, but I've not been able to figure out which one yet as I've undone most of what I changed and the issue persists.

I was unable to copy the crash log URL because after the force-close and restart, my clipboard was always empty. HERE is a logcat link. The first substantial systemui related error appears to start at line 4984 (in Notepad++ anyway), and I've pasted that first error group below. That error is repeated throughout the rest of the file as well as other errors.

I did a clean install, and I have no other mods installed, systemui or otherwise. I am going to try and dirty re-flash the Feb build to see if that might fix it, but I wanted to go ahead and drop off the log while it was on my mind.

Edit: I think I've figured out that it's the "Replace Clear all text with nice button" option in Quick Settings. As soon as I enable that option the crashes start, disable and it's fine.
