Anki on Linux not regaining focus after synching

Am currently on Anki 2.1.46 (94913ec2) on Linux Mint (20.2; the latest/current).
Python 3.8.1 Qt 5.15.1 PyQt 5.15.1.
I noticed this first on Anki 2.1.45, but did not post.

When I have learnt some cards in a deck, I return to the deck screen, and click on Sync. The little window describing the synchronisation pops up, but when it completes, the underlying home screen of Anki does not regain focus; it stays washed out.

Am trying to narrow down the exact steps that make this happen.

Obviously not a big problem, but thought you would like a heads-up.

Many thanks

It seems to be either a toolkit or window manager issue - it doesn’t seem to happen on the Mac I tested with here.

OK. Then we can wait and see, if a future version fixes it. It is not a problem, just a change in behaviour.
Thanks, @dae
