I started the program for the first time and noticed that all the labels and the interface itself look very blurry. The effect may increase or decrease, it is not clear why.
Restarting the program and changing the theme did not help.
A few folks Iβve seen are having this with hardware acceleration enabled under Obsidianβs settings->About.
Iβm guessing you have a NVidia graphics card. Iβve run through enabling high performance in Windows 11, turning off FXAA in the control panel, and working through the ClearText function, and all that worked was disabling the Hardware Acceleration.
