GNOME Bugzilla – Bug 596464
Some flashes appears when a window is resized
Last modified: 2020-11-06 20:08:19 UTC
Hello, I'm part of the Cairo-Dock team. Cairo-Dock is a dock using Cairo/OpenGL backend. It needs a composite support and it works almost well with Metacity. There is just one problem : some flashes appear (often) and the dock is moved quickly when the window used by Cairo-Dock is resized. In fact Cairo-Dock resizes its window when the dock is active. Can you have a look to this screencast? http://videobin.org/+fx/if.html It seems that it's an old bug but sorry for that, we have never report this bug here. I have tested on Gnome 2.26 and 2.28. Mutter is also affected by this bug This bug is much present now because the resizing is more used. You can find all informations about the installation of Cairo-Dock there : http://www.cairo-dock.org/ww_page.php?p=Accueil&lang=en#0-Installation The project page on launchpad : https://launchpad.net/cairo-dock Our source code : https://code.launchpad.net/cairo-dock Thanks for your help and many thanks for your great project! PS : I have reported this bug on Launchpad : https://bugs.launchpad.net/bugs/437378
I confirm that I've this bug with the version 2.30 too. Fabounet has given more details on LaunchPad: > to be more specific, I think the problem comes from the use of the > gdk_move_resize function, which resizes and moves the window at the same > time. > it just calls XMoveResize, and then the WM get the X message and do its job > (here, it probably does it in 2 times instead of 1).
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. If you can still reproduce this issue in a currently supported version of GNOME (currently that would be 3.38), then please feel free to report it at https://gitlab.gnome.org/GNOME/metacity/-/issues/ Thank you for reporting this issue and we are sorry it could not be fixed.
