Description
All the last builds after 16.0.0 of Qt Creator crash when using QT_QPA_PLATFORM=wayland. It happens when using the autocomplete functionality on some functions, but not on all of them. It was not happening with version 16.0.0.
Just as an example, it happens with std::to_string(). It crashes continuously with many, many functions. The terminal message after crash is the following:
qt.qpa.wayland: Failed to create popup. Ensure popup QWidgetWindow(0xe6fd760, name="QWidgetClassWindow") has a transientParent set.
The Wayland connection experienced a fatal error: Protocol error
The system log captured from gnome-log is the following:
gnome-shell: WL: error in client communication (pid 14618)
The system is: Fedora 42, Gnome, Wayland session, kernels 6.14 & 6.15, mesa 25.0.7 AMD drivers. I attach the output of the command qtdiag for more details. Is there any other detail/log that I can provide? It's a very annoying issue. Luckily, it doesn't happen with the platform xcb.
