Bug#1039440: xfwm4: Alt-tab and mouse-down do not shift focus
Package: xfwm4
Version: 4.18.0-1
Severity: important
X-Debbugs-Cc: budheal508@gmail.com
Dear Maintainer,
* What led up to the situation?
I fired jigdo with 2023-06-05 iso DLBDs mounted to scan, to build DVDs. This stresses the system, but not seriously. Since the scan step takes 40-45 minutes, the screen goes to sleep. System Monitor shows there is plenty of RAM but 1 or 2 of the CPU threads (of 8) are maxed.
* What exactly did you do (or not do) that was effective (or
ineffective)?
When awakening the screen, which is more or less instant upon moving the mouse, before jigdo-lite finishes (many hours on) a mousedown will not activate other windows. Sometimes it will take a few minutes to start recognize mouse clicks, although then it is responsive. Using alt-tab will activate a window, but clicks are ignored. The mouse wheel will scroll the old focus. For instance, to search related bugs I used alt-tab to activate a browser window and used keyboard navigation to look through the list.
Similar bugs are #629873 and #640842, but they do not mention trouble with alt-tab navigation.
As I am typing, I closed a number of applications and windows. Thunar hung on a window for an afp: server; I had disconnected the Ethernet in favor of a different network. This might be a part of the recipe but does not seem to be a part of the pudding.
* What was the outcome of this action?
The window manager goes on vacation. Even pressing the Power button had no fast response. I had to use tab to select Hibernate. Upon resumption, the error status was unaffected. Is the window manager getting lost in its events?
* What outcome did you expect instead?
XFCE should maintain focus in the active window and shift when activating a different one.
