Window in focus is blacked after fast switching of windows.

[xambroz]

Just realized the version in git is not exactly the same as on https://extensions.gnome.org/extension/97/coverflow-alt-tab/
I have tried with the version from git, but the results are the same.

This is the error when installing (or restarting gnome-shell):
JS ERROR: !!! WARNING: 'anonymous function does not always return a value'
JS ERROR: !!! WARNING: file '/home/mambroz/.local/share/gnome-shell/extensions/[email protected]/switcher.js' line 98 exception 0 number 157

This is the error when the issue occures:
Window manager warning: Log level 8: g_source_remove: assertion `tag > 0' failed
JS ERROR: !!! Exception was: TypeError: this._windows is null
JS ERROR: !!! message = '"this._windows is null"'
JS ERROR: !!! fileName = '"/home/mambroz/.local/share/gnome-shell/extensions/[email protected]/switcher.js"'
JS ERROR: !!! lineNumber = '171'
JS ERROR: !!! stack = '"()@/home/mambroz/.local/share/gnome-shell/extensions/[email protected]/switcher.js:171
()@/home/mambroz/.local/share/gnome-shell/extensions/[email protected]/switcher.js:159
"'

Sometimes this happens just after 2 alt-tab switches, and sometimes it takes 100 switches.

Thank you for the report! I can reproduce some similar behavior. Randomly when Alt-Tabbing fast, my windows disappear and there's just the desktop dimmed down. Is that what you mean?
I hope I can find a fix soon.

I have the exact same problem. When the window is chosen, the whole screen become black (or gray?). I have to restart gnome-shell to workaournd it. This happens to me 2 or more times per day. I am using the version in extensions.gnome.org.

PS: It's not related to this problem, but I see the following printout whenever I use "alt+tab":

JS LOG: The property transistion doesn't seem to be a normal object property of [0x26da4d0 ShellGenericContainer:last-child first-child insensitive "panel"] or a registered special property
Window manager warning: Log level 8: g_source_remove: assertion tag > 0' failed Window manager warning: Log level 8: g_source_remove: assertiontag > 0' failed
....

Can you please disable these warning messages somehow?

Regards,
Thank you very much.

Can you test the newest version from git and check if these issues still exist?

[sgon00]

I tried the git version. So far so good. If I meet the issue again, I will let you know. Btw, the failure messages still exist in the git version whenever using Alt+Tab. Is that possible to prevent it? Thanks a lot.

The warnings should be gone with the latest version.
