--- Comment #34 from sthe...@arcor.de --- I can confirm this bug in Kubuntu 17.04, KDE Plasma 5.9.4, KDE Framework 5.31.0, Qt 5.7.1. It appeared after installing a 1200x1920 display (yes, in portrait mode) in addition to two 1920x1200 displays (in landscape), giving a total resolution of 5040x1920. Symptoms as in Comment 13 and Comment 18. Setting the cursor theme/ pointer size only helps temporarily. The permanent fix for me is as described in Comment 32: System Settings/ Appearance/ Fonts/ [x] Force fonts DPI: 96 -- You are receiving this mail because: You are watching all bug changes.
