Activities overview broken on 20.04 LTS (3.36) with Pop Shell

[jacobgkau]

(1) Issue/Bug Description: When attempting to access the Activities overview on a 20.04 LTS machine (GNOME 3.36), no windows are shown and I cannot exit Activities:

I'm able to recover by restarting GNOME Shell. I get the following error in the logs:

Based on the error message, I believe this is caused by dc0e306, the final commit in #1069 that was not tested before merging (branch protection rules have since been added to prevent this from occurring again.)

(2) Steps to reproduce (if you know): Install the master branch of Pop Shell on a Pop!_OS 20.04 LTS system and open the Activities menu.

(3) Expected behavior: The Activities menu should function.

(4) Distribution (run cat /etc/os-release): Pop!_OS 20.04 LTS

(5) Gnome Shell version: 3.36

(6) Pop Shell version (run apt policy pop-shell or provide the latest commit if building locally):

• f4894c8 (master)
• 304cafd (default-methods)

(7) Where was Pop Shell installed from: Proposed PPA, staging repos.

(8) Monitor Setup (2 x 1080p, 4K, Primary(Horizontal), Secondary(Vertical), etc): 1080p internal + 1440p external.

(9) Other Installed/Enabled Extensions: Pop!_OS defaults only.

(10) Other Notes: N/A

I thought this might be what people in #1072 are experiencing on Ubuntu LTS, but the logs look different. None of their logs mention meta_window.get_wm_class.

I just rechecked my logs updated my comment in #1072 . I'm also seeing a meta_window.get_wm_class error

Thank you, that would have been nice to know. I'm closing this as a duplicate of #1072, I'm not seeing the recursion errors it's referring to but I do see the Activities menu issue on Ubuntu and Pop!_OS.
