I'm experiencing the same issue as you and trying to debug the problem. Did you make any progress on the issue?
Thanks for your answer,
Best Regards
]]>I have a Samsung Series 5 ultrabook (NP540U3C), with a touchscreen. Besides this issue, it works without any problems. I'm using gnome3.
If I have two windows open, I can touch the titlebar and move the window in focus. If I move it, and then tap to bring the second window into focus, and attempt to move the second window as well, my tap/drag moves the *first* window instead. Clicking via mouse on the second window doesn't help: grabbing any titlebar with the touchscreen will move that first window I dragged with the touchscreen. The only thing I can find that resets this behavior is switching to a virtual terminal and then back into X. Then, it's the same story: I am stuck only able to touch-move the first window whose titlebar I touch.
I don't see any of this behavior when working *within* windows (I can tap windows to focus, click elements inside, etc.), so I suspect this has something to do with mutter. Beyond that, though, I'm absolutely lost.
How can I proceed with finding what's going on here? Does anyone with a touchscreen see this sort of behavior? I have created a test user to double-check that it this problem shows up before my user's personal desktop configuration. The problem has been here since my latest switch to Arch a couple months ago; a recent upgrade isn't to blame.
As always, thanks for any help.
