I got a gen 3, basically what is not working are :
- Internal MIcrophone
- Back Camera
- Fingerprint reader
- FnLock key Everything else is working well enough so far for me. S2idle is working way more reliably on this device than on my SP4 but with a bit a tinkering I think that you can get S3 sleep working.
Qt has native support of fractional scaling both on X11 and wayland (wp-fractional-scale)
On the other hand GTK3/4 only support integer scaling. So on wayland it’s they are basically rendered at x2 and downscaled to your fractional scale factor.
