High power consumption bug with “use fixed list on home menu” disabled

Hi,

I spotted a strange problem with Black Glass Nova today while testing power consumption of a Vero4K running OSMC, and Krypton 17.1.

When “use fixed list on home menu” is disabled and in horizontal menu mode – which are both the default, the home screen is being redrawn every frame (60fps show in the debug overlay) which is causing increased CPU and GPU activity and increasing power consumption to 4 watts due to the CPU not being able to idle much.

When enabling visualizedirtyregions in advancedsettings.xml the bottom 1/3rd of the screen is a constant dark red indicating that this whole region is being redrawn every frame even though nothing is animating on the screen.

When I disable “use fixed list on home menu” this problem does not occur – the CPU can idle correctly and draws half as much power. visualizedirtyregions shows that the bottom 1/3rd of the screen is not being constantly refreshed and the average frame rate shown in the debug overlay is around 3-12 fps.

This high refresh rate of the bottom of the screen would seem to be a skin bug ? I don’t see any similar issues with Estuary or the OSMC skin, although neither of those have a setting equivalent to “use fixed list on home menu” due to their different designs.

PS thanks for this great skin – it has been my default skin in Kodi for about 2 years now. Smile
