[Bug Report/Feature request] Support for Boox devices

[eszter007]

Thanks for all your effort developing Kaku. It seems like it isn't compatible with Boox devices since the popup isn't shown. Resizing the window works but there is no content shown when tapping in the frame.

I use a Boox Poke 3 with Android 10, I use the Playstore version from the 9th May.
