Strange Visual Errors When Refining Selection Brush (Designer 1.10.8)

[Duwap]

I keep getting this kind of screen-tearing, pixelating error when zooming in and out while refining edges on a selection brush. I've tried closing and reopening Designer, and restarting my computer. Is anyone else seeing this happen?

MacOS version? - However, check under the ADe preferences the hardware performance acceleration settings, if Metal is setup there try with OpenGL instead in order to see if things may then behave differently.

See under Performance options (--> Hardware Acceleration):

@v_kyr Thank you for responding. The settings show it as already being in OpenGL mode for the hardware acceleration.

But "Enable Metal compute acceleration" is still checked! - Disable that and retry then again.

@v_kyr That fixed it! Thank you.
