Same here, all the clicks go to the previously focused window until right clicked (in a way that it will be registered in the previous window, clicking outside doesn't help), then the clicks are registered in the new window only. Closing previous window helps. e.g.: chrome with gmail opened in a tab, going to another desktop/alt-tabbing to another window, clicking inside the shown window registers clicks in gmail, right-clicking where emails list suppose to be registers in gmail and doesn't release the "lock" clicking somewhere in the body or where chrome tabs/menus suppose to be pops-up a context menu and releases the lock, closing/killing chrome helps too. All the clicks after that register in the new window only... Another scenario: when in not-maximized window, alt-tabbing/going to another desktop, clicking - all the clicks register in the previous window, right-clicking "outside" that window won't do anything, clicking inside releases the lock...
I'm pretty much sure that the reason right-click helps is that it creates the context menu, which is a window itself. So when a new window created it gets the focus and mouse clicks go there, clicking anywhere else closes the menu and window is destroyed, releasing that way the "lock". So any next window you click has the focus now... My setup - openSuSE 12.1 64, X 1.10.4, KDE 4.7.2R5 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/505494 Title: Mouse events fail frequently and unpredictably, requiring kwin restart Status in “xserver-xorg-input-evdev” package in Ubuntu: Confirmed Bug description: Binary package hint: kdebase-workspace There is confusion between a number of related bugs (which didn't show up for me in "Do any of the following bugs..."). Bug #478464 seems most similar to this but that's dubiously marked as a duplicate of bug #41301. DESCRIPTION It occurs within a few minutes (usually sooner) after starting KDE or restarting kwin with "kwin --replace". The mouse cursor continues to move where it should, but clicking either does nothing or affects an unexpected (inactive) window, and gestures such as pushing into the desktop corners also do nothing. It's as if kwin thinks the mouse cursor is frozen somewhere other than where it appears. Everything other than mouse events continues to work as expected: controlling KDE with keyboard shortcuts shows that applications, compositing and desktop effects are all fine. [Edit: it is NOT as if a phantom window/app is grabbing the mouse events, because as stated above, clicks occasionally still affect a real window for a short while, even if it's an inactive one.] WORKAROUND Restart kwin with "kwin --replace". None of the workarounds mentioned in the discussion for bug #41301 work for this, which is why I think it's different. BACKGROUND I'm not running Xinerama or dual screens, I have a USB mouse which works perfectly on my other machine, my Kubuntu 9.10 retains most of its default settings, windows are set to "Click to Focus", and my graphics card is nVidia GeForce 6100 with the nvidia-glx-185 driver. I run regular apt updates, and first noticed this bug on 8 Jan 2010, having run KDE with very few problems for several months. I think the automatic updates on 8 Jan were for Firefox and GIMP (upgrades), but this bug occurs whether or not Firefox or GIMP are running. I have not made any configuration changes recently.
