* Make sure your checkout of Krita trunk is completely up to date
* save sven's patch to your home directory
* go to koffice/krita/plugins/paintops/libbrush
* execude this command in that directory: "patch -p0 < ~/qtconcurrentmask.diff"

then make and install as usual. For added responsiveness, build in kritadevs mode, not the default debug mode. This is a switch for cmake: -DCMAKE_BUILD_TYPE=KritaDevs

Something like:


Now I noticed from your screenshot that you have almost all debug messages enabled. If you find and install an application called "kdebugdialog" (I am not sure where in *buntu or mint that is) you can run that, check the "disable all debug output" checkbox and press ok.
