Magnifier stuck randomly
Last modified: 2014-01-16 16:24:36 UTC
Created attachment 254594 [details] the settings window Hi, I often use the screen magnifier of the gnome shell. Since the 3.8. the magnifier focus begins to stuck randomly. i can use the mouse, the focus doesnt follow the mouse but the mouse seems to move.the screen also seems not to freeze: if i move the mouse left on the top ( to activate the shell overview) the overview appears and i can see the overview. Only the fucus stuck for sometimes 20 seconds. if i restart the shell (alt + f2 -> r -> return) the magnifier mostly works again correct. i use the fullscreen mode on the magnifier.
Hi Chris, thank you for reporting this. Could you get a stack trace for this?
Hi Magdalen, Maybe :). How can i do this?
You must have a spare computer and ssh into the computer with the problem. There are some instructions here https://wiki.gnome.org/GnomeShell/Debugging but let me know if there are any problems and I will try to help if I can do. I am not sure if some of the problem (not the freezing) is related to your gsetting though... what comes back from $ gsettings get org.gnome.desktop.a11y.magnifier mouse-tracking ?
Thanks, Ok i ll try to debug it tomorrow. $ gsettings get org.gnome.desktop.a11y.magnifier mouse-tracking 'proportional' $

As a test anyway could you please try $ gsettings set org.gnome.desktop.a11y.magnifier mouse-tracking push and $ gsettings set org.gnome.desktop.a11y.magnifier mouse-tracking centered Just to see if that reduces any of the issues for you? You can put it back with $ gsettings set org.gnome.desktop.a11y.magnifier mouse-tracking proportional if it does not help. I am thinking a longer term improvement would be to include an option to magnify a smaller area because it seems the magnifier does not like it when some of the coordinates go out, but I don't know if that is connected to this problem here to be honest. you will need to remotely go into your machine to get the backtrace, do you know how to do that ok?
1I think this can be closed. i does not have the problem since my Fedora update 19 -> 20. So in gnome 3.10.x i cant see the problem anymore. if i have this problem again i ll tell you. thanks for your help!
OK. Please reopen if the issue reintroduces itself :-)
