this is a very special behaviour on a special setup. We will not be able to track this down soon, I am sorry. We may look at it for a certain amount of project sponsoring. Please let me know if that is an option for you (or your company in case you use X2Go at work).

Thank you for your answer. I cannot help you with sponsoring unfortunately. However I did some further investigations and I believe this issue might be more general than it looks like, I think it applies to all multiple screen scenarios where session type is single application. It should therefore be much easier to reproduce than anticipated.

I retested this without a portrait screen but rather a classical dual monitor setup, that is two landscape monitors next to each other. At same resolution ("identical screens") there is no problem with the context menu placement when being close to the bottom edge. But the placement is wrong when being close to the right edge of the left screen. With different resolutions of the screens the behaviour is always consistent with the larger vertical resolution.

My suggestion for the error source is that the bottom right corner of the ENTIRE area available is used when the placement of the context menu is decided, rather than the bottom right corner of the individual screen. All tests with various resolutions, orientations and placements of the screens are consistent with that. Let me add that this happens both with and without the Xinerama option turned on.

I hope this information can help tracking the issue down. Kind regards, Daniel

I just wanted to let you know that Ulrich Sibiller is currently
working on the Xinerama bits in nx-libs. I am very confident that he
will find a way to fix your issue.

Mike
