I got it to work on ONDA v820W V3 with Arch Linux x86_64 chroot, which should be similar to Jolla Tablet. If you create nemo user with UID 100000, kwin_wayland can be started as nemo. It's also possible to start kwin_wayland as sole compositor, not nested in lipstick, to get OpenGL in Wayland/Xorg with i915/MESA, but it often crashes on start, probably due to some differences in kernel DRM subsystem for Android's Intel UFO driver.
