Hi,
On my side that it works nice under ubuntu 20.04TLS. (on a VM !) - I remove completely older version of skia (I had trouble on linux side (different than yours @Serge_G - lib load issue - But origin is on my side, I make mess 😉)),
-> I just done the update via getit in 3.40, and Skia4Delphi demo app work nice !
@vfbb : very very nice work !
