Pretty much since update to Bluez-5 with its in-tree SixAxis/DS3 support
I've been experiencing this strange bug: about every minute both axises
of both sticks "jump" to their lowest position for one "frame" and then
back to normal. It only behaves like that under bluez 5, connected
wirelessly, and never under Windows® or via USB.
Here's some data:

Surely I don't need to elaborate on how useless it makes the device.
PS: Isn't its time already to get bluez a bugtracker ? It's unbelievable
how much bullshit one has to hoop over just to officially complain on
it. No wonder that bluez userspace always has been one of most broken,
unfinished, unreliable, un-userfriendly pieces of FOSS code ever. Or
maybe it's all inherited from Bluetooth® mess of a standard and it's
destined to suck.
