http://bugzilla.opensuse.org/show_bug.cgi?id=986066 Bug ID: 986066 Summary: Mouse wheel events sometimes go to the wrong window Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.1 Hardware: x86-64 OS: openSUSE 42.1 Status: NEW Severity: Normal Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: opensuse-kde-bugs@opensuse.org Reporter: winkelmann@hornetsecurity.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:47.0) Gecko/20100101 Firefox/47.0 Build Identifier: Ever since booting up today, mouse wheel events in Plasma 5 sometimes get sent to the wrong window. When I use the mouse wheel to scroll the content in any window that allows scrolling, scrolling will work for some time until suddenly, quite randomly, some other open window will start scrolling. For example, when scrolling in Firefox, suddenly instead of the Firefox window keeping on scrolling, the Konsole window next to it will scroll through its command history. A lot of the time, the scroll events seem to erroneously go to the window list or the desktop, meaning I end up switching through the open windows or the virtual desktops. This only started happening today, but unfortunately, I cannot say which update might have brought this on, since I hadn't rebooted in some time (weeks, maybe a month) before that. (I am using OpenSuse in VirtualBox, and I usually just freeze the VM instead of doing a real shutdown. I did a real shutdown yesterday because there was a kernel update.) I am not moving the mouse out of the window I am trying to scroll or otherwise making it lose focus. Scrolling using the arrow keys works or by dragging the scroll bar works fine. Reproducible: Sometimes Steps to Reproduce: 1. Have several windows open that allow scrolling using the mouse wheel. 2. Move the mouse cursor into one of those windows and activate it (if not using focus-follows-mouse anyway). 3. Scroll the content for a while, back and forth, without moving the mouse cursor Actual Results: The selected window may scroll is content for some time. After some time, or sometimes immediately, other windows will start scrolling instead, or other windows will get brought to the foreground and start scrolling or the virtual desktops will be switched. Expected Results: As long as the mouse cursor stays in the original window, the mouse wheel should only scroll content in that window, never in any others and never the window list or the virtual desktops. OpenSuse is running in a virtual machine under VirtualBox, in turn running under MS Windows 10. The problem has never occured before this morning, but since then has been persistent. -- You are receiving this mail because: You are on the CC list for the bug.
