Wine – snapshot effect issue

Description of problem: Once clicked onto the title bar of an application
emulated by Wine in order to enlarge its respective window, all the windows
already opened then on the same desktop, including the window of the
application whose title bar has been clicked on, are suddenly and for the
duration of the wine session set as part of the desktop active background
picture.

Version-Release number of selected component in Fedora 27:
wine-2.20-1.fc27.x86_64

Steps to Reproduce in terminal:
$ sudo dnf install -y wine
$ wget https://www.grc.com/files/DNSBench.exe
$ wine DNSBench.exe (alternatively click the respective execute file)

Actual results: Result is similar to a snapshot of the desktop background at a
definite time, which in that case corresponds to the time the operation of
clicking the title bar of an application emulated by Wine was accomplished.

As noticeable the width of the title bar of the emulated application's enlarged
window does not correspond to the width of enlarged window. See attachment.

Expected results: No snapshot effect. The width of the title bar of the
emulated application's enlarged window to correspond to the width of enlarged
window.
