Looking at what -arb does specially, it has a "sizeFudge" parameter in the demo. If I avoid setting that, it all works fine with -arb as well. sizeFudge is used to reduce the size of the texture. Normally the texture is 512x512, but if I reduce it to 511x511, then things look much better (the 90 pixels that ought to be blacked out aren't, but at least the main stuff updates seemingly correctly.) And I'm seeing [ 3360.231160] nouveau E[ PGRAPH][0000:02:00.0] ERROR nsource: DATA_ERROR nstatus: BAD_ARGUMENT [ 3360.231173] nouveau E[ PGRAPH][0000:02:00.0] ch 3 [0x00118000 fbotexture[782]] subc 7 class 0x4097 mthd 0x0208 data 0x08080345 method 0x0208 = NV30_3D_RT_FORMAT. The problem is the type -- it's set to both linear *and* swizzle. A bit of investigation shows that this happens in nv30_clear. fb->cbufs[0]->texture is swizzled, but fb->zsbuf->texture is not. Not really sure how to handle this properly... I think fb->zsbuf->texture is not swizzled because it's a NPOT texture. (And if I make everything be 511x511, then everything becomes NPOT, and so the copy/etc succeeds.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
