Wargaming.net Game Center doesn't crash for me, but it gives a black screen as
in bug 48618. --disable-gpu is a workaround.

I did the regression test for Origin between wine 5.5 and wine 5.7 and the
commit that make the 'qtwebengineprocess.exe' crashes appear is commit 2b0977f.
Reverting that commit suppresses all the 'qtwebengineprocess.exe' error
dialogs, but the commit deals with dbghelp only, so may be it simply made the
real issue show.

Wine 5.8 improves the experience with Origin, as the 'qtwebengineprocess.exe'
errors only happens sometimes when the program closes. The window renders
correctly, though, so it's probably different issues.

Regards.
