[OnePlus 3T ROMs, Kernels, Recoveries, & Other Deve] Julian_os:
I guess that's the exact same issue I m facing. Still, here are the logs [MENTION=4405529]nvertigo67[/MENTION]:

One thing I noticed is that the following line appeared like every 0.75 seconds or something:

W/sh: type=1400 audit(0.0:6767): avc: denied { read } for name="stat" dev="proc" ino=4026532335 scontext=u:r:shell:s0 tcontext=u:object_r:proc_stat:s0 tclass=file permissive=0

In addition to that, there were no logging events when switching the alert slider (actually moving the button).

Though, here is what I get opening the dialog for setting a position to an alert mode (middle position):
