Compiz' Put plugin makes random mistakes in moving maximize windows between displays

[Huji Lee]

When using the Put plugin in Compiz to send a window to the next dispaly (the option is called "Put To Next Output"), sometimes Put fails as follows: It moves the window to the next output (animated), then suddenly the window jumps back to the prevoius display.

At least in my case, this only happens with Maximized windows. Interestingly, repeating the same operation a couple of times (without even resizing the window) will eventually lead to the expect behaviour.

Note that (as shown in the attached files), my two displays are not of exactly the same size (23 inch versus 22 inch), but they both use the same resolution. I doubt if that is the root cause (because of similar resolution) but I still wanted to point it out.

I am not aware of any way to log the behaviour, but if provided guidance, I would be willing to record such logs.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug has plagued me for years. In addition to when the window is maximized, a window will bounce back if the window was previously placed by the Compiz Grid plugin. The workaround is to restore the window before putting it to the next output. However, this is obnoxious. I can't believe this bug has not been fixed in all these years.
