Bug ID: 403911 Summary: Background is visible through 1-pixel "cracks" on 4K display Product: konsole Version: 18.04.3 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: konsole-de...@kde.org Reporter: sti...@att.net Target Milestone: --- Created attachment 117819 --> https://bugs.kde.org/attachment.cgi?id=117819&action=edit Screenshot SUMMARY See the attached screenshot - there are two 1-pixel bright blue vertical lines on the right, near the scroll back + 1 horizontal line at the bottom, between the Konsole's window and the panel. These 1-pixel lines are actually desktop's background image showing through the Konsole window. One of the vertical lines (left one) is sometimes repainted black - but a scroll-up in history brings it back. I am not sure if it is konsole's bug or window manager's - please reclassify if necessary. I don't see this issue on a 1920x1080 screen, only on 3840x2160 - which makes me think there is a rounding error somewhere... STEPS TO REPRODUCE 1. Install Kubuntu on a system with 4K screen 2. Run Konsole and maximize the window 3. Observe OBSERVED RESULT 1-pixel wide lines of background image inside Konsole's window. EXPECTED RESULT Konsole's window covering the whole window's area.
