Hi..
Anybody using Opera browser here? For me, the taskbar context menu for Opera (the menu you get when right-clicking on the taskbar entry for an application), takes about 2-3 seconds to appear.
I believe this happened ever since that update to KDE which supported 'jump lists'. But I cannot be sure since too many things have been updated in the past weeks (including Opera). There are no issues with context menus for Akgerator, Firefox, Thunderbird, Filezilla etc.
Thanks,
Syam
