Review request for Plasma.


Repository: kwin


Description
-------

Qt::AA_NoHighDpiScaling has been replaced with another HighDpi scale enabler/disabler at Qt 5.6 branch (qt5.git submodule already updated)

https://codereview.qt-project.org/#/c/127895/

This case build error with Qt 5.6 branch as following.
-----
/home/kenya888/devel/kf5/src/kde/workspace/kwin/main_wayland.cpp: In function 'int main(int, char**)':
/home/kenya888/devel/kf5/src/kde/workspace/kwin/main_wayland.cpp:379:36: error: 'AA_NoHighDpiScaling' is not a member of 'Qt'
     QCoreApplication::setAttribute(Qt::AA_NoHighDpiScaling, true);

-----

This patch fix this use Qt::AA_DisableHighDpiScaling instead of it.

Testing
-------

Build succeeded. Some test are failed, I know Martin is working about kwin wayland forcused on Qt 5.4. More investigation for test error is needed by myself. At the moment I'd like to avoid simply build error.

As reference, I'll paste ninja test log. tested with Qt 5.6 branch latest.
