From af9ec8a76d7e62444fadb518256fc58723fe5186 Mon Sep 17 00:00:00 2001 From: Johan Klokkhammer Helsing Date: Wed, 5 Jun 2019 13:10:38 +0200 Subject: [PATCH 3/8] Client: Don't add all windows to activePopups Neither Qt::ToolTip nor Qt::Popup are single bits in Qt::WindowFlags, and do in fact include Qt::Window. This meant that when we or'ed them and did a bitwise and with QWindow::type(), we would match more types than just Qt::Popup and Qt::ToolTip. We would for instance get any Qt::Window as well, which meant the main window would be added to activePopups, leading to strange things happening, such as crashes and the main window closing unexpectedly. [ChangeLog][QPA plugin] Fixed a crash when closing multiple popups at once.
