Found out that the on-screen keyboard in Gnome 3.30 behaves differently under X and Wayland. Non-gnome toolkits can't trigger it automatically when selecting text widgets, so it needs to be manually activated.
- Wayland: Swipe up from bottom of screen. Works but difficult to discover
- X: This gesture does not work and another way to activate is needed, discussed in bug #1760399 (the one from the prev. comment.)
- Both: In Gnome 3.30 even selecting Gnome text widgets only rarely triggers it automatically
