Hi. After updating from 2018.12-1 to 2019.4-1 I got a very low resolution and went to system to change resolution. Just after selecting “System” under “Settings” I got a splash screen asking if I want to keep the resolution.
So far the same thing hasn’t happened again after selecting a resolution but I remembered a different scenario with this happening to @iainf in [TESTING] Kodi v18 release builds
Hopefully this log will help.
