A handful tests in Qt Base fail on Wayland:

1. 297 - tst_qwindow (Failed)
2. 308 - tst_qshortcut_kernel (Failed)
3. 328 - tst_qbrush (Failed)
4. 385 - tst_qopengl (Failed)
5. 386 - tst_qvulkan (Failed)
6. 442 - tst_qdialog (Failed)
7. 452 - tst_qgraphicseffect (Failed)
8. 492 - tst_qwidget_window (Failed)
9. 498 - tst_qwidget (Failed)
10. 499 - tst_qshortcut (Failed)
11. 519 - tst_qdockwidget (Failed)
12. 530 - tst_qpushbutton (Failed)
13. 564 - tst_qaccessibility (Failed)

The following also fail, but fail when running on X11 as well for me, so for now we can assume it might be false positives:

1. 175 - tst_qdate (Failed)
2. 295 - tst_qscreen (Failed)
3. 427 - tst_qprinterinfo (Failed)
4. 446 - tst_qinputdialog (Failed)
5. 516 - tst_qdatetimeedit (Failed)
6. 529 - tst_qprogressbar (Failed)

The following fails only on X11 and not with Wayland, which is strange and should be checked:

1. 555 - tst_qopenglwidget (Failed)
