After the latest stable update overview no longer shows any open applications. Any ideas how to fix it?

2

Do not enable Dash to Dock in the same time with Dash to Panel … Keep only one, log out and back in after change.

Thanks, but I prefer that they are both on, but for some reason I rebooted again and this time it shows the open apps.

Update:

I had just left my laptop on standby and came back and the overview doesn’t show the apps again.

This might not be the solution but do you have this in your logs:

I’ve had 2 instances of a empty overview and visual ‘lockup’ and just disabled the native window placement extension to check if that is the cause of the issue I am currently looking into, this could have nothing to do with your issue.

How exactly do I view these logs?

7

This command below in a terminal will show the line with this error in the log and the 4 lines after it:
journalctl | grep -A 4 "JS ERROR: TypeError: app is null"

This could be wild goose chase, does the advice given by bogdancovaciu help in any way ?

8

I tried the command you gave but it came up with nothing.

I didn’t try bogdancovaciu’s advice since I wanted to keep both turned on. But throughout the day the problem seems to come and go. Sometimes it works fine when I press the Super key, sometimes it shows nothing.

Solution: open gnome extension ( extensions.gnome . org/local/ ) and disable Pop Shell

It starts with last packages upgrade and updates installed new system extension (Pop Shell) and I found out this error in journal.

in console:
gnome-extensions disable pop-shell@system76.com

I can confirm that @sodae 's solution worked perfectly in my case. After enabling Pop Shell extension back, the issue once again started appearing.

As a side note: Dash to Dock and Dash to Panel were disabled for the whole time.

If they conflict they conflict - and your preference is not going to change that.

If your preference is creating issues - change your preference.

This should do - sudo journalctl -p 0…3

13

But they don’t conflict. It has worked fine for years. And for some weird reason, it doesn’t seem to be happening anymore.

14

I never had pop shell enabled ever. I tried it but it was already disabled. For some reason I’m not getting the bug anymore. I think turning off dash to dock once and turning it back on fixed it. I’m not sure.
