DRI PRIME doesn't always work with intel/radeon

Description

Hello.
I am running Ubuntu 16.04, with MATE installed later on it, using the latter currently. Beside normal system updates, I am using the Mesa stable ppa.
Recently I started using DRI_PRIME=1 in some cases, to make the AMD videocard working. I found that it doesn't always work and the Intel one is used instead, like DRI_PRIME didn't even matter to it. This happens with Unigine Heaven, Steam and even glxinfo.
Strangely, glxgears is not affected, it always does what it should be.
I cannot reproduce this behaviour, it just happens sometimes. And it seems to solve itself after a reboot.
Tell me, what you need to look into it.
Thanks.
