[SOLVED] QT Creator crashes after a while on Wayland Plasma

QT Creator starts and works fine for around 5 minutes but then abruptly crashes. The crash doesn't seem to correspond to any particular activity within the app, except that splitting the view appears to hasten it. It doesn't crash if I use Plasma with X.

This is what it says in the command line:

$ qtcreator
Icon theme "gnome" not found.
Icon theme "ubuntu-mono-dark" not found.
Icon theme "Mint-X" not found.
Icon theme "elementary" not found.
Icon theme "gnome" not found.
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
ConnectionServer error: "QLocalSocket: Remote closed" "/tmp/QtCreator-hUbTfz/ClangBackEnd-14503"
Segmentation fault (core dumped)

And here's the dump:

While using X suffices for a workaround, but any help fixing this would be appreciated.

It appears that somewhere along the line updates fixed the issue.
