CopyQ completely crashes sway (IPC failure on Wayland)

Created on 14 Aug 2020 · 3Comments · Source: hluk/CopyQ

Describe the bug
Around 30% of the time when I bring up CopyQ's paste window, the receiving app crashes, pulling down a few other apps. Sometimes all processes crash, sometimes only the window that was last focused.

Same happens when CopyQ window is successfully opened, and I select an entry. Just as I select it, CopyQ crashes together with the receiving app and some others.

As I mostly paste to firefox, that's where I had most of the crashes, but it also happened in some electron apps.

The crash is not just killing the receiving app, but it somehow makes it impossible to start the crashed app again. Immediately after crashing, in my surviving terminal I can try to start the crashed program again (e.g. firefox) and the command just gets stuck, nothing happens, no logs output anywhere, it's just blocked.

I have been noticing this for over a month, I've updates all software to latest versions, and I have found no other combination of software or commands used or provoking such a crash.

When it crashes, logs of my DE sway show A LOT of errors:

[2020-07-27 17:49:56.813] [error] Window: Invalid IPC magic

To Reproduce
Steps to reproduce the behavior:

Start sway
Open firefox
Open copyq and try to paste an entry to firefox
If everything is still working (firefox still running), go to (3)
Bang!

Expected behavior
CopyQ pastes the selected entry to the receiving app

What I have tried:

looking for information in other issues here (#27 , #926 , ...)
starting copyq with unset QT_QPA_PLATFORMTHEME and with envvar QT_QPA_PLATFORM=xcb and all variations of those two
