After about 1 hour working fine, the failure is present again, so the previous workaround of setting Tearing prevention (vsync) to 'never' no longer worked. I experimented again with some display settings and found that setting Rendering Engine to XRender, instead of OpenGL 2.0 or OpenGL 3.1 solves the failure, at least for now.
