RestoreSceneSizeTest fails on Ubuntu 24.04 and same test doesn't fail in Ubuntu 22.04 with same FX code.

RestoreSceneSizeTest > testUnfullscreenSize() FAILED

Increasing sleep times in test has no effect and it looks like we have some product bug for Ubuntu24.04.
This behaviour is seen in both Wayland and Xorg in Ubuntu 24.04.
