If that's the problem, I'd definitely urge you to try the latest
pretest, since AFAIK some of these problems are supposed to be solved
there (as part of handling bug#20432 you mention).

Why do you need the "export" parts?  Isn't the following enough?

 $ GDK_SCALE=1 GDK_DPI_SCALE=1 emacs

I think it might already be fixed, please try the latest pretest, or
build from the emacs-25 branch of the Emacs repository.

In any case, I added to PROBLEMS the description of this and the
workaround.

Thanks.
