I'm pretty sure this is depth related - the dump unfortunately doesn't include the board, which must've been rendered in a previous frame. A frame dump while using the software renderer would be helpful.

That said, the minz and maxz are both set to exactly 0, and I think some accuracy issue is causing the top left (which does use zero depth values) not render.

Last bad v1.13.1-289-ga35d26190 First good v1.13.1-291-g8d0c84bf0 That mean #15845 It is simple workaround for fix for another game. Not sure can close

That should be fixed once #15858 is in, since the feature that #15845 fixes goes away and is replaced with a different method to achieve the same thing.

@benderscruffy Can you try v1.13.1-381-g5046cbd01 ?

sum2012 avatar Aug 21 '22 08:08 sum2012

still happens in v1.13.1-381-g5046cbd01

benderscruffy avatar Aug 21 '22 09:08 benderscruffy

@benderscruffy How about v1.13.1-291-g8d0c84bf0 ?

sum2012 avatar Aug 21 '22 09:08 sum2012

Strangely, even the software renderer frame dumps have black sections (the texture is black.) I suspect this game renders the board either on CPU or to a temporary buffer, and then just textures from that. Somehow, some parts of that are coming out black.

It could be a misdetected framebuffer suboffset. That said, I don't see why software would have black textures...

Hm, got a similar report through e-mail that looks a little bit different:

Like the others, this is not likely to be specific to your old pc, so I'm reopening.
