QT6 OpenGL left right inverted

I wrote a maze generator with QT5.

I am trying to modify the source code for QT6.

I corrected the source code to compile with QT6.

But I noticed an error between the maze map and the view in 3D(OpenGL) on the map I should turn left and on the 3d view I turn right.

I uploaded the project there. It is an open source project.

To be sure, you should ensure that the maze view rotation logic matches the way you handle movement in 3D space. Check to see if you need to apply a 180 degree rotation or axis flip to fix the problem.

I don't know

I replaced x by -x in several lines that display walls. It is working.
