To be clear the fonts are also slightly misshapen at 100% and even have a slight oscillation of darkness at 100%, as will always be the case unless the characters were spaced an exact integer of pixels apart. My point is that it looks worse on the scaled examples. Also sorry for how many separate comments I'm adding, I just want to make sure everything is clear. -- You are receiving this mail because: You are the assignee for the bug.

Fonts in browsers look perfect no matter the scaling (if they are not perfect it is not noticeable, unlike in LibreOffice where it is very noticeable to me). Graphical applications can display pixel perfect graphics, bypassing system scaling and implementing their own, as long as fractional scaling is set the same on all monitors – there is currently a bug in KDE Plasma that means if Global Scaling is different on different monitors that will break scaling. LibreOffice is also affected by this, except it always renders fonts wrong as long as fractional scaling is used at all, on any monitor. Importantly though, with a single monitor using fractional scaling, fonts will be misshapen. As I said in my previous comment, the misshapen characters are back, and I will upload another comparison example, making sure to only use a single monitor so as not to allow any system bugs to affect the test. -- You are receiving this mail because: You are the assignee for the bug.

At some point there was an update and fonts once again seems more misshapen than blurry. -- You are receiving this mail because: You are the assignee for the bug.
