Description Paul Menzel 2018-02-12 11:53:13 UTC 
Using LibreOffice 6.0.1.1 on GNU/Linux with an Intel HD Graphics 530 (i7-6700) the modesetting driver doing a simple transition like wipe on the HiDPI/4K monitor Dell U2718Q, it is not smooth but you can see how every line is drawn. This is visible in editing and presentation mode.

Comment 2 Paul Menzel 2018-02-14 14:40:09 UTC 
I was able to reproduce this on two non-HiDPI monitors with resolution of 1920 x 1080, where one system has an Nvidia card with proprietary Nvidia driver 390.25, and the other is a TUXEDO Book BU1406 with an Intel Kaby Lake graphics device and Ubuntu 17.10.

completly smooth (buth with rendering artifacts) here on an AMD Kaveri APU / mesa 17.2.4

Mesa 17.3.3 here. How do I find out, if OpenGL is used?

Maybe my terminology is wrong. I see how each line is basically drawn, which is smooth.

Could you describe the rendering artifacts?
