Created attachment 127422 [details] Screenshot showing the issue. SUMMARY When running with 150% screen scaling, the cursor has a 1 px white (it's probably not white, but "undefined" border on the right side.) STEPS TO REPRODUCE 1. Set scaling factor to 1.5 in System Settings 2. Open Konsole 3. Change to a different directory -- this seems to trigger it reliably OBSERVED RESULT Blinking cursor with a 1 pixel wide border on the right EXPECTED RESULT No white border SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Created attachment 127423 [details] Screenshot showing the issue. This is the issue -- notice the one pixel border on the right hand side of the block cursor.
The border is btw 1 *transparent* pixel wide, so you can see the window *below* through it. That it's white was just a coincidence. The same issue appears in the menu, the "black" line next to "Help" is in fact the same kind of 1 pixel transparent line.
I also noticed that this is font-dependent. With different fonts, I also get horizontal lines appearing; sometimes below links, sometimes across the full width. If I had to guess, I'd say some font metric is rounded (line height/width) and does not match the actual glyph size.

horizontal lines is a known bug, see bug 373232.
