<!-- Describe the issue -->
I've upgraded to BitcoinQt 0.16.1 and now I can't minimize to tray.
Expected behavior
Check the setting and it work.
Reproducing
I don't really know if this is a problem with gnome in Ubuntu 18.04.1 LTS, but this is an almost clean installation (reinstalled +- 1w ago). I downloaded the compiled binary from https://bitcoin.org/en/download and verified the signature/hash. Installed following the steps given in the webpage. Tried to mark the Window options to minimize to tray, but It only works once. After you open the window it doesn't minimize to tray again, even with the settings checked.
