--- Comment #8 from Thorsten Oppels <thopp...@web.de> --- KDevelop is affected, too. Same behavior. (openSUSE 15.0 and openSUSE 15.1) This is with Nvidia Graphics. With some unknows reason the scale ratio is set to 1.1. then I see the horizontal lines. When set the scale factor to 1.0 the lines are not seen but all windows, strings, icons are LARGER, then smaller. If I go back to scale factor 1.1 the size of my desktop seems OK but the horizontal lines are back ... Because this behavior seems to be since 2016 ... How needs scaling? Which config files are affected? Whats the original values? Is there a documentation how it works? -- You are receiving this mail because: You are watching all bug changes.
