Comment (by athrxx):

 Do these glitches only occur in mixed speech/text mode?

 In the ticket you're saying "i tried different options, changing driver,
 among other things, and always seems to happen". But the attached videos
 all seem to be from mixed speech/text mode.

 This is probably a regression. The mixed mode was not supported in the
 original game and does certain things that have to be worked around (like
 drawing portraits above the view port boundaries). We did have a different
 workaround for the out-of-bounds-drawing which is no longer usable with
 the changed graphics code. The one we have now apparently does not catch
 all cases...

 The window overlay glitch is a bit more annoying. The original interpreter
 does have specific code to restore hires graphics after closing a window.
 Which the original probably never needed, since the devs ditched the mixed
 speech/text mode, anyway. Implementing that restoring code might fix that
 issue.

 No idea about no. 4, but that also seems to be specific to the mixed
 speech/text mode.
