freeze?

Anyone with tablet randomly "Completely frozen" (no autoreboot, forced to press power-on button)? , especially using Chrome (And in other programs also, more likely when loading some image).

With CM13 this did not happen.

And why the Mali GPU driver was again OpenGL ES 3.0? (CM 14.1 : 3.0, CM13 : 3.1)

This seems to be when the freeze starts (kmsg log):

Sorry for causing any problems.

But the freeze passes almost daily.

And it seems to me go back to CM13 :crying: , (someone knows about an option for multiwindow?).

Attaching the syslog app results.

Edit: Tablet is SM-P900, Actually with CM14.1 (11-Feb-2017) . The freeze occurred on all versions of CM14 that I tested (as I said randomly (1 day ~ 3 days), sometimes freezing to the first lock screen after rebooting)
