--- Comment #1 from Yichao Yu <yyc1...@gmail.com> ---
I'm still not sure what's changed but the issue seems to be caused by showing a
widget before a parent is set.
In `app/viewmainpage.cpp`, `mThumbnailBar` was created without a parent and may
be set to visible immediately after creation before it is added to
`mThumbnailSplitter`. This caused a toplevel `QXcbWindow` to be created for it.
The following patch fixes/works around the issue.
```
diff --git a/app/viewmainpage.cpp b/app/viewmainpage.cpp

```
This seems to be fairly harmless. I'm not sure though if this is supposed to be
working.
