Wayland
Users of the Wayland, a computer protocol which specifies the communication between a display server (called a Wayland compositor) and its clients, may find that there are some glitches in RawTherapee's user interface, for example all comboboxes (such as the Processing Profiles selector, the Film Simulation drop-down, etc.) work correctly only the first time they are used, and then do not respond until RawTherapee is restarted. This is not a bug in RawTherapee.
Reports indicate that the cause is an incompatibility between GTK+ and the Wayland compositor.
Users of the following distributions are most likely affected:
- Fedora >=25
- Ubuntu 17.10 (Ubuntu 18.04 reverted to X11 due to Wayland issues)
Affected users are advised to:
- Try switching the compositor to Weston.
- Revert to X11 if problems persist.
