I am building SatNav device running Rpi 3B+ and of course Emteria OS. I would like to use two navigation SW - MapFactor Navigator and Waze.
MapFactor Nav allows to chose type of map rendering - software or hardware. If I chose software rendering then MapFactor works well without problems. But hardware rendering causes freezing whole system and only turning off and on helps.
Waze is probably using only hardware rendering and it causes freezing of system too and in addition rendering often causes black white flashing of displayed map. All other displayed elements are OK, only map is randomly disappearing and flashing. I think, it is easily reproducible with zoom out button. If map is well zoomed out, then it starts to flash.
I tried to modify various OpenGL parameters in build.prop file and various graphics developer settings but nothing helps. It looks as Emteria has serious problems with using of GPU for rendering.
My last experiment was to try competing Raspberry Android build - RaspAnd (Oreo build) with installed Waze. RaspAnd Oreo build is practically unusable because of performance reasons but Waze is working without rendering issues there.
So my question is: Is possible to update graphics subsystem drivers/libraries in Emteria OS? Because it looks as new Oreo is working well.
