Something must be very wrong with your graphic driver as you have submitted three reports about OpenGL issues now. It's probably best to check for updates of the graphic driver, first.

Maybe, maybe not. All I can say is that I have no drawing artifacts with 0.17.
However, it also crashes with the steps explained above.
I cannot update my card drivers. They are included in MacOS X and cannot be updated separately. My card is a built-in Intel Iris...

v0.17 uses Qt4 and v0.18 supports Qt5 and Qt4.

The Qt developers have more or less completely reworked the support of OpenGL and the Qt-API to it in Qt5.x.
I think under the hood they use some more modern OpenGL techniques now but this requires that the system OpenGL driver is properly implemented. If not, there is nothing we can do on our side to improve this.

Unfortunately, it's a known fact that Apple doesn't put much effort any more in improving this. They even declared OpenGL as deprecated because they want to push their Metal API.
