context menus of applications are sometimes drawn outside visible area

[Timo Juhani Lindfors]

This is probably a known problem but I could not find a bug report about it.

If I right-click an URL in quassel IRC client I get a context menu. If the URL is on the last line of the window then the last entries of the context menu are drawn outside the visible area of the desktop :-)

I need to manually move the window and then right-click to be able to access the menu.

see how the "Copy Link Address" context menu entry is not visible at all (it is below visiable area)

As you may have guessed, this happens because the application is drawing onto a virtual screen which is bigger than the one it eventually gets displayed on. The application and its widgets think that the space below is actually usable and shown to the user when it's not.

The best (and only?) solution is to resize the virtual screen to match the client's. The code already exists, however, to make use of it you will need a virtual screen which supports randr. The only viable option at present is ​Xdummy.
There is already a winswitch bug describing this: ​replace Xvfb with Xvnc or Xdummy

My ​original post describing how to use Xdummy with xpra is no longer up to date as the '--xvfb' switch has now been changed to specify the full command and arguments, which makes it a little easier.

As for the next step, I would like to make Xdummy a proper first class package, removing the need to resort to LD_PRELOAD tricks to start it, etc - see #10. Until then, this will remain a manual setup process..

See #2 for a potential workaround, the real solution is #10 - closing.
