Strange freezing on Acer Iconia One 10

Hello everybody,

I am experiencing strange freezes on Acer Iconia One 10, while testing a mini game developed in Godot 3.0. I’ve tested it on a number of other devices without experiencing similar issues. The freezers happen every few seconds and last for a few seconds.
Profiling didn’t report any frame drops or errors.

I can see similar freezes while running Godot 2D demo projects on the tablet in question.

I’ve attached the logcat of approximately when the issue happens:

I also see a big usage of Video Memory that I cannot explain since the app has a single Texture Atlas with all graphical elements 2048x2048, and two themes with dynamic font.

I am not attributing the freezes to video memory since as I’ve said I see similar issues with Godot Demo projects that have minimal video memory footprint.

Acer usually has some analytic and information collection software on their devices, you know, to improve your experience. I have not owned an Acer for quite some time but I have found it to not play to well with other engines. So I would make sure no Acer bloatware is running in the background.

I can’t remember the name of it but there is one that constantly scans everything. I don’t know if they still use it or not.

Another culprit could be antivirus.

I killed all the processes I could get to, but I still have the same issues. I’ve attached the logcat of approximately when the issue happens:

I’ve started a slow process of porting the app to Godot 2.1.x and at this time I can say that the freezing is gone.
It might mean that GLES3 was not properly implemented on this device.
I tried Godot 3.1 version that I compiled from the master branch and built the app with GLES2, but the freezing still happened, so I cannot be sure.
