A few folks I’ve seen are having this with hardware acceleration enabled under Obsidian’s settings->About.
I’m guessing you have a NVidia graphics card. I’ve 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.
