   Betreff: [X2Go-Dev] Broken glyphs and icons after suspending a session
        An: x2go-dev@lists.berlios.de

Hello x2go dev team,

as I was looking for an alternative on NX nomachine, because it was
broken with the last Cairo 1.12 update, I found your x2go solution,
which is great.

So as it bases on the same libraries than the original nomachine, you
had the same issues - with rendering to undrawable objects, the whole
nxagent crashes because of SEGV.

With the patch of Jan (thanks to) you committed to the master branch
today, I compiled another nxagent. Actually it worked fine, but after
suspending and reconnecting to a session, some graphical objects get
broken...

All characters/fonts that has been rendered on the screen prior the
suspension, are gone. (See Screenshots the link below).
Creating new text by starting applications is ok, as long as the
characters has not been rendered in the session before.

I thought it might be problem with a kind of glyph cache of the X
session (ubuntu/x86 x2goclient). But I found one case, where
additionally to the text, all icons are gone also, which was with an
debian/x64 x2goclient... (Difference can be seen on screenshots)

Might it have to do something with the patch from today, that could
filter out to much rendering? Or is this issue known from somewhere else?

Here are some screenshots: http://www.computerfreak.de/sonic/x2shots/

Thanks for your help,
Holger

Hi!

 The same happens on my machine after upgrading from OpenSuSE 12.1 to 12.2.
 QT-Programs seem to be less affected than GTK-Programs and Gnome in
particular.

Fixed in release nx-libs 3.5.0.15.

nx-libs (2:3.5.0.15-0) unstable; urgency=low

  * Improve 020_add-nxagent-wrapper.full.patch: Properly set NX_TEMP, make
    sure nxagent launches even with pam_tmpdir.so being in use.
  * Improve 023_add-x2goagent-wrapper.full.patch: Properly set NX_TEMP, make
    sure x2goagent launches even with pam_tmpdir.so being in use.
  * Add VERSION.x2goagent to package x2goagent package so x2goversion command
    lists up x2goagent in the list of X2Go server-side packages.
  * Refresh patch: 200_nxagent_check-binary-x2go-flavour.full.patch.
  * Make sure the NX_TEMP envvar gets set in all wrapper script for all nx*
    execubles.
  * Link libNX_Xrandr to a separate location where we can provide it as
    libXrandr.
  * /debian/control:
    + Maintainer change in package: X2Go Developers  
<x2go-dev@lists.berlios.de>.
    + Priority: optional.
  * Add patch: 220_nxproxy-bind-loopback-only.full+lite.patch, adds loopback
    option to nxproxy options and forces nxproxy to bind to loopback devices
    only.

  [ Oleksandr Shneyder ]
  * Add patch: 204-nxagent_repaint-solidpict.full.patch. Fixes repainting of
    SolidFill pictures by nxagent/x2goagent on reconnects. Closes upstream
    issue #16.
