I am using PVRHub on a rooted Nexus 5 (Android 5.1.1).
When I initiate a PVRTrace from PVRHub, the traced GLES2 applications opens as expected, but when I close the app and return to PVRHub no trace has been saved. I notice in the PVRTrace settings in PVRHub the save file location is greyed out and cannot be changed, though the documentation implies that it can. I do not have this problem with PVRTune - a file is created and seems to work fine.
While installing PVRTune from PVRHub, the phone failed to reboot on its own and the rotating installation circle spinned indefinitely, so I had to manually reboot. Not sure if this is a sign of an improper installation, but the in-app instructions said a manual reboot may be required so I am guessing it is OK.
Atached is the relevant logcat from trying to PVRTrace an app (pianoroll), as well as my device info.
Edit: Text file attachments aren’t accepted for ‘security reasons’? Ok, here is the info:

Using PVRHub 2…2, which came bundled with the PowerVR SDK 3.5 x64 for Linux.

Would it be possible for you to create a ticket on our support portal and attach the apk binary for the application? We will try to reproduce the issue from there.
