[snap] Chromium hangs and is unstable in reproducible ways

[Abonnementspaul]

As described on this issue: https://bugs.chromium.org/p/chromium/issues/detail?id=1256489

Briefly, moving around selected text from the browser and opening comboboxes are very prone to make the browser freeze for a minute or so.

The binaries distributed by Canonical via Snap do not behave as expected. Google Chrome builds and AppImage Chromium builds do. This issue did not occur weeks ago.

I believe the issue comes from the build from Canonical. Issue reproduced with Snap builds from Stable and Beta channels.

Thanks for the report! I tried reproducing the problem on my machine, but comboboxes on https://www.lvmh.fr/talents/nous-rejoindre/nos-offres/liste-des-offres/ don't freeze chromium.

Could you please run `apport-collect 1946156` to attach additional information to this bug, which might help reproducing and investigating? Thanks!

[Abonnementspaul (abonnementspaul)]

Thank you for your time. Apport runs into an issue:

```
$ apport-collect 1946156
Package chromium-browser not installed and no hook available, ignoring
```

Indeed chromium-browser is not installed on the machine since I'm using Snap. Is there a workaround I could use to provide additional information?

[Olivier Tilloy (osomon)]

That's unfortunate indeed. Could you please attach the output of the following commands?

    lsb_release -a

    env | grep -i _session

    snap info --abs-time chromium

    snap info --abs-time gtk-common-themes

    snap info --abs-time core18

    snap connections chromium

Thanks!

I'm having a similar issue here. I'm Ubuntu 21.10, Wayland, AMD cpu with integrated radeon.
Whenever I right click, I get an empty menu, and chromium freezes. Maybe related to this:
