window changes location between toggles

**Describe the bug**
Toggling copyq via `copyq toggle` opens the window ever lower and to the right of previous window location, eventually wrapping and starting from the center again.

**To Reproduce**
Toggle the window constantly and observe the window movement between the toggles.

**Expected behavior**
Window should open & close without changing its position

**Version, OS and Environment**
```
$ copyq --version

Qt: 6.10.2
KNotifications: 6.23.0
Compiler: GCC
Arch: x86_64-little_endian-lp64

```

Running x11, no desktop env, using i3 window manager.

Unsure when exactly this started happening, it's been a few months at least.
Reproduces both in single-mon & multi-mon setups.
