      Title. When running Qt Creator under native Wayland, and I hover over anything and it shows a tooltip, I get a segfault. Specifically, I get the error:

       

      ConnectionServer error: "QLocalSocket: Remote closed" "/tmp/QtCreator-tuleQY/ClangBackEnd-25111"
fish: "qtcreator" terminated by signal SIGSEGV (Address boundary error)

      Running it as

      qtcreator -platform xcb

      as in, forcing it to run under XWayland, fixes this issue.
