SUMMARY
Some distro (eg slackware, suse) use a "mixed" wayland session, where both the
xcb and the wayland platforms are available. Basically each app can decide to
start as pure wayland or inside XWayland using xcb.
When spectacle is run in XWayland, it is not able to grab rectangle regions.
STEPS TO REPRODUCE
1. run spectacle with the xcb platform inside a wayland session
2. try to grab a rectangular region
OBSERVED RESULT
The correct wayland platform is loaded by looking at XDG_SESSION_TYPE, but
something goes wrong during the screen grab.
Console output:
Error calling KWin DBus interface:
"org.kde.kwin.Screenshot.Error.ScreenMissing" "Screen not found"
EXPECTED RESULT
A rectangle region grab
