Description
I'm using Pyside6 6.7.2 on Linux (Fedora 40) installed using pip. I'm doing some testings with `Qt3DExtras.QText2DEntity`. Attached on this bug report there a simple test I'm using. On Macos (Arm M1) this test in running OK, without problems. But on Linux I'm having problems. This is output error:
