           Summary: Regnum Online only works in safe mode
           Product: Mesa
           Version: git
          Platform: Other
               URL: http://www.regnumonline.com.ar/
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: sa@whiz.se


The game Regnum Online (MMO but can be downloaded and played at no cost), only
runs if "Safe Mode" is selected in the options. 

With r300c, I get these errors:

drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See
dmesg for more info.
Found 4 messages leaked

[...]

[ 9468.240398] radeon 0000:01:00.0: (PW 1) Vertex array 0 need 268396832 dwords

[ 9468.240404] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

With r300g, the game starts, but doesn't render correctly (see attached
screenshot).

The game is run with "Fixed pipeline" set in the options, using shaders will
apprently need the new glsl2 compiler.

Screenshot of bug in RO in safe mode

Even safe mode isn't working perfectly. Every few seconds all characters
flickers and seems to lose their shape. The attached screenshot shows the bug.

It looks like a new issue, can you bisect it?

This is odd, I can only reproduce it with some of the games NPCs now, not my
own character. I'm not really sure what has changed from yesterday, but I guess
it's possible that some update to the game has changed the behaviour.

Doesn't seem to be a new bug though, I can reproduce it with the same checkout
as I used in my initial bug report. Probably didn't notice it then, or forgot
to mention it.

The bug seems to have something to do with the angle or location from which I
look at an NPC, shifting slightly to the right or left will either show it
rendered properly, or corrupt.

The bug in safe mode (the one in the screenshot) goes away if RADEON_NO_TCL=1
is set.

The bug with corrupted vertices appears to be fixed.

Regnum with shader backend

(In reply to comment #6)
> The bug with corrupted vertices appears to be fixed.

Indeed, the fixed function backend seems to be working fine now.


The shader backend is still busted (screenshot attached). Not sure if it's
relevant, but Intel has been making some progress on that end:

Is this still an issue with the latest mesa from git?

The game is still busted, but this is not specific to r300g but a problem with
the GLSL compiler. There's already bug 28138 open about this, but that's filed
against i965 and Intel is making some progress there, but only on their own
backend.

It's probably easier to close this report and file a new one against Mesa core
to keep things simple.
