Description of problem:

ReText crashes after being initialized as soon as mouse hovers its window.

Version-Release number of selected component (if applicable):

retext-7.1.0-7.fc35.noarch

How reproducible:

100% of the times the application is initialized.

Steps to Reproduce:

I have Fedora 35 with all the latest updates available as of now. I am running GNOME3 with Wayland on an Intel integrated graphics card in a Lenovo T490 laptop.

When I start ReText, I get the following messages on the console:

$ retext

The ReText window comes up, but as soon as my mouse pointer hovers over it, the application crashes and the following is printed in the console:

QPainter::begin: A paint device can only be painted by one painter at a time.
QPainter::setCompositionMode: Painter not active

Actual results:

ReText always crashes when initalized.

Expected results:

ReText should initialize without issues.
