--- Comment #2 from CnZhx <z...@cnzhx.net> --- Hi Friedrich, thank you for looking into this. To answer your questions, a) That means the "Force fonts DPI" in "Fonts" of the system is set to 168, and the "Screen Scaling" in "Display and Monitor" is set to 1. This is because the following reason. I have a 14" laptop with WQHD display. On the one hand, with screen scaling of 2, the items on screen are too big so less content can be displayed. But screen scaling of fractional value (e.g. 1.3) could cause problems with Konsole and so on. On the other hand, I use an external monitor now and then. It has a normal DPI of 96. If I set screen scaling to value larger than 1, elements on the external screen would be too large. Then, I increase fonts DPI only to make fonts big enough to read (the Fonts sizes are kept default, e.g. Noto Sans 10 for General). b) I tried your method to run Kate. The display is just the same as I reported. In addition to this, I guess it's helpful to mention that I use a font size of 10 in Kate (font family: Hack), which is on the left side of the screenshot. I would expect the preview of Markdown using sizes of symbol (actual font/character size) based on visual font size in system settings. So I include another screenshot with comparison for your reference. Please refer to the next comment. -- You are receiving this mail because: You are watching all bug changes.
