bug#41519: 26.3; transient-mark-mode + WSL + vcxsrv clobbers clipboard

[Crawford, Christopher]

[-- Attachment #1: Type: text/plain, Size: 5949 bytes --]

In a fresh 'emacs -q',
whenever I highlight text with the mouse, or S-<right>, or C-spc <right?,
etc, emacs copies the text into the Windows clipboard, and I can't disable
it.  This means that I cannot highlight text in Emacs and replace it with
text previously copied from a Windows program.  I'm running on Ubuntu 18.04
on WSL using VcXsrv.  I've tried every combination of
  transient-mark-mode
  shift-selection-mode
  save-interprogram-paste-before-kill
with no success.
If I disable  select-enable-clipboard , it won't paste from the clipboard,
and setting  select-enable-primary  also doesn't seem to matter.

bug#41519: 26.3; transient-mark-mode + WSL + vcxsrv clobbers clipboard

I don't think this is an Emacs bug.  Emacs puts the selected text into
the X selection; I'm guessing that some WSL agent then copies that
selection into the Windows clipboard.  This doesn't happen when
running on Windows natively.

Did you try setting select-active-regions to nil?

Thanks for your help, and you are right:  disabling  select-active-regions
fixes it.
Prompted by your response, I found an option in VcXsrv, "Clipboard may use
PRIMARY selection" (right-clicking on the server icon) which could also be
disabled to allow cut and paste between Windows and Emacs without
clobbering the clipboard.

Thanks, so I guess this bug can be closed now?
