Thanks for reporting, quite strange this one. Maybe it's somehow failing to clear the border of the shadow texture, or the projection math is subtly wrong...

Is it the same in the software renderer?

UltraGamerTR commented 8 months ago

It sure is. Here's the screenshot with software renderer. (Vulkan) shadow

Here's the frame capture of it. Hope this helps! shadow_glitch_soft_render.zip
