--- Comment #11 from Sebastian Lackner <sebastian at fds-team.de> ---
After taking a closer look I have finally figured out whats going wrong:

This is (as I already suspected) a bug in the QT implementation - they have
messed up the order of the arguments when they pass them to sendXEmbedMessage()
*sic*

I have setup a test environment, and confirmed that the following "workaround"
patch solves this problem - feel free to test it yourself, too:
http://source.winehq.org/patches/data/101921

Nevertheless this means that basically the whole XEmbed implementation which
recently got upstream into Wine will not be used for VST plugins!

@ Tobias:

If you prefer to have XEmbed working the "right" way I can help you guys to fix
the issues in a fork, if you want to. I can provide patches for the most
critical issues in there if you give me a few days, but it will most likely not
be compatible with "regular" QT applications, that expect the wrong behaviour
(except we can get all the bugfixes upstream). You can contact me either via
mail or even better just join our channel #pipelight on IRC freenode (nickname:
slackner). ;-)
