Alt + tab freezes screen
Using alt tab sometimes freezes the whole screen and there is no way to solve it unless you force restart the PC
Same here, in my case the only other option rather than force restarting is force closing all programs (ALT + F4)

i just stopped using the extension
I had the same problem under gnome 45, but it turns out that it was due to a conflict with another extension which also triggered when I did alt+tab,
Do you think this could also be the case for you?
Sorry for my silence on this issue. I have never had a freeze myself. It probably is not a bug in the extension, but likely as @JE-Amouel suggests caused with a conflict with another extension.
Can anyone with this issue send steps to reproduce?
For me personally, I can no longer reproduce this issue so it seems kind of weird. Anyway here are the extensions that I use and these are not the cause of conflict.
For me the conflict occurs with aatws which is also an alt+tab switch, and which also provides a dock mode which I find much more productive, so I do not use the alt+tab with this extension, and i prefer to use alt+tab with coverflow.
On version 42.9 of GNOME, the two extensions do not conflict, coverflow overwrite the alt+tab behavior of aatw, so I can use coverflow with alt+tab and at the same time , aatws with is dock mode. But on GNOME versions 45+, when I install aatws and coverflow the two conflict; reason why I made this feature request #239
so the steps to reproduce on my side are:
- install aatws
- install coverflow
- press alt+tab
On my system the freeze is nondeterministic. But it occurred with ALT-TAB as well as SUPER-TAB. If I wait after such freeze up to the system goes to sleep, the desktop is fully responsible again after waking up system.
I have activated the logging of the extension and found a NULL pointer access violation by the extension. If the extension freeze, it died every time with the same exception (log is in reverse order):

Hopefully, it can help you a little bit to find the bug. Used Version: CoverflowAltTab v75 under Arch Linux with gnome-shell 46.4.
@Sputnik2a Thank you for the logs!!! That's the best clue I have so far on this issue.
It's a strange issue, but I can try a fix that might stop the crash without me understanding the reason it's happening, which is unsatisfying, but better than crashes.
@Sputnik2a and all, I have committed something to the main branch that might fix this issue. Can anyone try it out?
Hi All, I think with version 76, I have fixed the freezes. I understand why they were happening, too! Let me know if you try it and it fixes things for you please!
@Sputnik2a special thanks for those logs. They were the clue that I needed!
@dsheeler You're welcome.
I had patched your commit 940b2a95 into my local v75 installation and tested it the last days. No freeze 😎 nor any side effect. Now, I test it with v76. Thanks for your great work.
I'm using version 76. Occasionally, the window freezes, and in very rare cases, the entire desktop crashes. The following is the log information.

@wonderfulyeah, thanks for the report. I haven't seen this one yet. I'll have to think about why this might be happening.
