My environment in which this problem occurs:

I am using SecureCRT 8.0.3 on a Dell laptop running Windows 10 to connect
via ssh to a Fedora 25 Linux system. The laptop is running VcXsrv 1.15.2.0
as its X server, which is where the blank buffer content is displayed.

Thanks for testing.

Daniel, could you please look into this?  If this is something specific to
this particular X server, and it cannot be fixed/worked around in Emacs
sources, perhaps we need a run-time option to disable double-buffering for a
certain display?
