Summary: Heroes of Newerth: Setting shader quality to medium results in corrupt rendering Product: Mesa Version: git Platform: Other URL: http://www.heroesofnewerth.com/ OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: sa@whiz.se

Created an attachment (id=38673) --> (https://bugs.freedesktop.org/attachment.cgi?id=38673) Screenshot on medium setting

In the game Heroes of Newerth, turning the setting "Shader Quality" to medium or high results in corrupt rendering of water.

This seems to be a regression from the glsl2 merge, but it seems fine on llvmpipe, so I'm guessing the bug is specific to r300g.

I _think_ it's possible to reproduce this bug without buying the game, by only registering and then either starting a practice game or running the tutorial. If not, I'll see about getting some trial invites.

The rest of the effects in the game seems to be working fine.

Hmm... I get a different result with noopt, the corruption is less noticeable, mostly in the borders around the water, but the actual visual effect seems to be missing.

I'm attaching a log with RADEON_DEBUG=noopt,fp,vp

No difference with or without setting RADEON_NO_TCL as far as I can see.

This patch with noopt seems to be the best result yet.

I made a bunch of screenshots, comparing llvmpipe with master, master+noopt, the patch, and the patch+noopt: http://www.flickr.com/photos/whizse/

Thanks, this was helpful. Can you post the output of RADEON_DEBUG=fp on master with both medium and high settings.

Also, is there any chance that this is a regression that can be bisected?

Done

The regression happened right after the glsl2 merge. I don't think it's possible to pinpoint it down any further.

The problem remains (corrupt rendering with medium and high) but seems to be slightly different now. I have uploaded new screenshots:

high: http://www.flickr.com/photos/whizse/5201781578/

medium: http://www.flickr.com/photos/whizse/5201187031/

all previous screenshots are here, for comparison: http://www.flickr.com/photos/whizse/

I also noticed this error message: r300: ERROR: FS input generic 17 unassigned, not enough hardware slots.

Let me know if you need new debug dumps or screenshots with noopt.

There's still a problem with rendering issues when shader quality is set to anything higher than "Low". I was just wondering if this is related to the hardware limitation (the "FS input generic 17 unassigned" warning) rather than bug?

--- Comment #23 from Marek Olšák maraeo@gmail.com 2011-02-23 06:34:31 PST --- It could be. That FS input may contain random values because it's uninitialized, potentially leading to pixels being influenced by it, resulting in sort of random corruption. It depends on the shader and how much the input contributes to the final pixel color.
