Minimizing a maximized Qt app leaves nothing in focus

[Omer Akram]

I tried with every gtk+ app but did not happen. This only happens with non-gtk apps, tried Kdenlive and qbittorrent and thunderbird.

TEST CASE:
1. Open any application e.g. terminal and maximize it.
2. Now opena QT application(qbittorrent for example) and Maximize.
3. Minimize qbittorrent

WHAT HAPPENS:
no app is shown as 'in focus' in the menu bar.

WHAT SHOULD HAPPEN:
minimizing qbittorrent should give focus to the app behind it, in this case chromium, there should be no need to click in the chromium window to get it to focus

See the video attached for better understanding of the bug report please.

sorry for the confusion I can still reliably reproduce this bug on my netbook, did a clean install just two days ago.
