Hello, 

sorry it took so long to answer, but it was time for some holidays, and the 
laptop is not coming with us.

As I see things, I only have problems when 2 windows from a GNUStep application 
overlap, with and without GWorkspace. I find no issues with non-GNUStep 
applications, or when one of the applications is not a GNUStep application.

It looks as though parts of the window that are redrawn during the scrolling up 
remain on the screen. I attached a photograph I took from the screen, because 
the problem does not show up when I take a screenshot.

(and another remark onGNUStep: attaching a file seems not to be working 
completely: it is just including the file in the mail)

There is no error scrolling down. The process is a bit 'flickery' but the 
result is correct.

Of course, if I'm the only one to notice this, it might also be something with 
my installation of GNUStep. 


For FreeBSD, I have the following version (uname -a)

    FreeBSD ottopedi 11.1-RELEASE-p1 FreeBSD 11.1-RELEASE-p1 #0: Wed Aug  9 
11:17:49 UTC 2017            
root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  i386
 
For GNUstep, following versions are installed: 

    libgnustep-base.so.1.25.0
    libgnustep-gui.so.0.25.1
    libgnustep-back-025.bundle
