+Subject: BUG:406032 Fix crash caused by unsupported composition mode in QT
+ 5.12
+
+Qt 5.12 doesn't support QPainter::RasterOp_SourceXorDestination anymore.
+
+Trying to paint with a painter that uses this while opengl is enabled
+will lead to a crash. The only relevant place this enum value is still used
+is in kis_tool.cc, where it is only painted on the regular non-accelerated canvas.
+
+Anyhow, told the smartpatch to use this function instead of doing something itself.
+
+The whole thing is a little bizar.
