[winswitch] [ANNOUNCE] Xpra 4.0.4: many fixes, one critical

[Antoine Martin]

Hi,


This update fixes quite a few bugs, in particular:

* a server-side memory leak
* an auto-refresh bug causing windows to remain blurry
* errors with some 64-bit MS Windows client configurations
* file-transfer fixes

And much more. Updating is strongly recommended.


Note: to prevent some X11 desktop crashes seen only with Debian and
Ubuntu, the packaging for those two distributions has been changed to
use Xvfb instead of Xdummy.
This may result in less accurate DPI and font sizes.
You can switch back to Xdummy by modifying
/etc/xpra/conf.d/55_server_x11.conf
(this is not a bug in xpra but the fact that xpra can trigger it makes
it our problem)

Full release notes:
* fix memory leak with 'scroll' encoding
* fix NVENC encoder (profile errors)
* fix unmanaged X11 message call which could cause GTK to crash when it
fails
