New description:

 I had an installation of SCUMMVM version 2.2.0 on my PC with Windows 11.
 I uninstalled this one and then I installed the newer version 2.5.1.
 Unfortunately, it displays corrupted graphics even when starting the GUI.
 I reinstalled version 2.2.0 and it is working fine again.
 I downloaded and tested also the candidate release 2.6.0 and it also shows
 corrupted graphics.
 Next, I cloned the latest sources of the repository, I compiled them
 myself and I'm still getting wrong graphics.
 But, if I configure with --opengl-mode=none, then the bug disappears.
 I remember that in the past I got exactly the same issue with VICE
 emulator and it was caused by an error into the R/G/B/A masks.
 I debugged for an hour this issue with VisualStudio, but unluckly I was
 not yet able to find the cause.
 I hope that you could help me to find a solution. Thank you.

 Sincerely.
