[arch-general] Patch for qt5-wayland to fix extreme lag on wayland

Hi folks,

I use wayland on plasma and it's extremely laggy. I googled and see this patch https://codereview.qt-project.org/c/qt/qtwayland/+/373473.

I rebuild qt5-wayland and it worked very well. But the patch leads to race condition.

I wonder that maintainer of qt5-wayland should include to PKGBUILD or not.

Best regards, Severus
