Public bug reported:
I am not really sure this is an Xorg problem. Since my last system
update (upon the system prompting), I think less than a week ago, I have
noticed this troubling intermittent behavior. I go to drag (mouse-
initiated) a window across some screen distances (between external
monitors and my laptop's builtin monitor) the window will get dropped
without me releasing the mouse button before arriving at my desired drop
point. More than half the times this happens, something will immediately
be picked up in a drag operation. Sometimes it is another window that
begins being moved. Other times it is a window resize operation that is
picked up. A third option is the selection of text.
I have noticed that most of the time it is triggered when I am moving
rapidly (though no more rapidly than I have done successfully in the
past). Sometimes it happens when I pause during the drag operation. It
even happens infrequently when I am dragging slowly.
Often I can just go back and pick up the window and complete the
operation. However, sometimes the problem just keeps happening until I
give up and go away for 5 minutes or so.
I have a stock configuration of 20.04. I keep it updated and haven't
changed anything significant about X, Gnome, etc. I have done a few
tweaks, but nothing I can think of that would relate to this problem. My
laptop, a Dell XPS 13, uses a USB 3.1 hub and through that drives two
monitors via HDMI. My mouse is bluetooth - Logitech MX Vertical. I don't
believe I have installed any proprietary drivers. My 3 displays are
arranged into an inverted "L" shape, as the laptop display is "below"
and identically sized to the 27" monitor "above" it. The other 27"
monitor is to the left of the first one.
Some, potentially useful, debugging info:
