Thin black lines bordering foviated area with quadviews

[Roosterfeet]

I see thin black lines bordering the foviated area when using quadviews. Not a deal breaker but I would certainly prefer not to have them. Has anyone else encountered that?

Here are my quadviews settings:

turbo_mode=1
smoothen_focus_view_edges=0.2
sharpen_focus_view=0
peripheral_multiplier=0.5
focus_multiplier=1
horizontal_fixed_section=0.45
vertical_fixed_section=0.9
vertical_fixed_offset=0

Are you using QV Companion? Maybe your focus edge is too sharp? Companion lets you set that in pixels.
