GNOME Bugzilla – Bug 458558
Interaction with wireless mices
Last modified: 2020-11-06 20:07:33 UTC
Please describe the problem: When dragging a window vertically on the screen, the movement is very jumpy/choppy. Other windowmanagers such as kwin does not present this problem. Steps to reproduce: 1. Get a wireless mouse (I tried "Logitech Cordless trackman" and "Logitech Cordless MouseMan Optical") 2. Start X 3. Start xterm 4. Start metacity 5. ---> Use the mouse, click on the xterm window caption and drag it vertically 6. ---> Observe the 'jumpy' movement. of the window. 7. Drag it orizontally and see that the movement is smooth. 8. Right click on the caption and select "move" 9. Move your mouse vertically, and see that the movement is smooth again. 10. Try kwin --replace, and see that the movement is smooth. Actual results: Not smooth window dragging in vertical direction. Expected results: Smooth window dragging in both directions. Does this happen every time? Yes. Other information:
The problem goes away if i use a wired usb mouse, i also tried to play with various setting related to the mouse in xorg.conf such as mouse protocol, resolution, baudrate and samplerate in Xorg.conf, but the problem persists.
Firinel: you have a wireless mouse and I don't; would you mind testing and confirming this?
Though I can confirm that dragging a window vertically on the screen results in the movement be rather choppy, it's my experience that this is also the case when moving it in any direction (ie: not limited to only vertical momvement).
Firinel, could you please try to click with the right mouse button in the metacity window caption and select "move"? From that moment on, you could use the keyboard arrow keys to move the window around; that way it is smooth to me, so i spotted the problem to lies in the mouse. Thank you.
I've done so and the movement remains jerky for me, moving in any directions. When using the keys, if you just press once, I suppose it could be said to move smoothly, but if you hold it down, as if to move a greater distance, the movement is just as choppy, if not more so, as with the mouse.
Thank you anyway for trying, i can add some more info: -The problem appears on 32 and 64 bit version of Sabayon Linux (based on Gentoo) and Ubuntu (both 32 and 64bit), on the same hardware. - Today i tried with ubuntu on a laptop, and i noticed the same thing when using the touchpad, it was less noticable, but the vertical dragging were definitely not as smooth as the orizontal ones. Moving windows by keyboard or by a usb mouse were smooth on the laptop too. ----- I must say that i tried xfce also (xfwm4 --replace), and i noticed the same weird behavior, so probably that thing is not (only?) metacity-related. ----- Someone could please tell me a way to spot the problem?
bugzilla.gnome.org is being replaced by gitlab.gnome.org. We are closing all old bug reports in Bugzilla which have not seen updates for many years.
