Arch Linux

My last update was on 01.05.2020 and after that I've updated on 11.05.2020. Here are list of relevant packages which were updated (actually looks like simple `pkgrel` bump with the exception of `adwaita-qt` theme):
- qt5-base (5.14.2-1 -> 5.14.2-2)
- qt5-location (5.14.2-1 -> 5.14.2-2)
- qt5-webengine (5.14.2-1 -> 5.14.2-3)
- qt5-webkit (5.212.0alpha4-3 -> 5.212.0alpha4-4)
- adwaita-qt (1.1.1-1 -> 1.1.2-1)
- xorg-xset (1.2.4-1 -> 1.2.4-2)
- xorg-bdftopcf (1.1-1 -> 1.1-2)
- xorg-server-common (1.20.8-1 -> 1.20.8-2)
- xorg-server (1.20.8-1 -> 1.20.8-2)
- xorg-xmessage (1.0.5-1 -> 1.0.5-2)

I'm on cinnamon 4.6.0-2 (cinnamon-session 4.6.0-1) and it starts with `exec cinnamon-session` incantation in `.xinitrc`. Today when I started SimpleScreenRecorder (ver 0.4.1-1) it complained about non-X11 session:
```
You are using a non-X11 window system (e.g. Wayland) which is currently not supported by SimpleScreenRecorder. Several features will most likely not work properly. In order to solve this, you should log out, choose a X11/Xorg session at the login screen, and then log back in.
```

Some investigation lead me to a simplest check which gives false result:
```
#include <QtCore/QtCore>
#include <QtX11Extras/QX11Info>
#include <iostream>

int main(int argc, char *argv[]) {
std::cout << "Qt version: " << qVersion() << std::endl;
std::cout << "Are we using X11? " << QX11Info::isPlatformX11() << std::endl;

return 0;
}
```
After compiling it with `g++ -o main main.cpp -I/usr/include/qt -lQt5Core -lQt5X11Extras -fPIC` and running I have the following result:
```
Qt version: 5.14.2
Are we using X11? 0
```

Seems like a regression in some package after update
