First of all, sorry for not thoroughly reading the release notes in my rush to share the news; this was mentioned in there.
I checked, without doing your suggestion, I got these values:
W:\Android\platform-tools>adb shell getprop vendor.hwc.compose_policy
0
W:\Android\platform-tools>adb shell getprop persist.sys.keystone.display.id
-1
After your suggestion, the vendor.hwc.compose_policy is showing 6. But it’s not persistent, after a reboot it’s back to 0. What’s the thought behind implementing it this way, and is this definitive? To ask the Kodi user to do this after every reboot will grow tiresome, it would be great for heavy Kodi users like myself to be able to save the setting.
