<sarbes> It is just one bit, so it can't be a "classic" swizzle. Besides, there are already documented swizzle bits (swap rb, reverse component order). I think it is highly unlikely to find others.

<uis> I thought it is verilog bit range, bits 6 to 15. Tiled-linear bit probably was discovered already too.

<sarbes> The bit seems to add a small (.5 ?) s/t pixel offset to the kmscube RGBA texture.
<sarbes> Looking at Midgard v4, some documented bits which might explain the behaviour seem to be unused.

<anarsoul> sarbes: does it have any effect on non-depth textures?
<anarsoul> I mean the bit
<uis> Maybe GL/DX texture coordinates switch?
<uis> They are offset 0.5 pixels from each other
<anarsoul> maybe, IIRC Utgard should support DX9
