Myst III Exile: missing scene transition effect on PowerPC (big-endian) machines under AmigaOS4 — at Initial Version

Description
While testing AmigaOS4 builds of ScummVM (v2.5.0 and daily build from 25.12.2021) find out a rendering issue.
the issue is that switch between scenes in Myst3 does not have that nice transition effect when one scene is replaced by another one. instead, we have or just a white screen for a time while the transition effect should happen or a bit of visual trash (depends on the drivers we use).
if we use an older version of our drivers called MiniGL we have such a visuall mess:

if watch carefully between switching of scenes then instead of effect we have some purple vertical lines all over the screen for a time of effect.
And that if I use another more modern OpenGL driver called GL4ES:

There all visibly better. just instead of a color mess, we have a white screen for the time while the effect should happen and then a new scene happens.
When I test the same version of the game but on win32/x64 then all fine means it's probably a Big-Endian issue.
if you need any more details or tests just ask :)
Thanks!
