The reworked patch is now in master, along with a new checkbox for X11 
and Windows users.

I would be grateful of a KDE/X11 user could try to install a translucid 
windows theme like Layan and check
1/ that it creates display issues
2/ that the new checkbox in Preferences|Display fixes it (at the cost of 
losing subpixel aliasing).

This is candidate for 2.3.7 (by default it does nothing).
