             Bug #: 782
           Summary: Tutti-frutti bug for textures whose height isn't a
                    power of 2
    Classification: Unclassified
           Product: Odamex
           Version: 0.6-dev
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P1
         Component: Client
        AssignedTo: odamex-bug-reporter@xxxxxxxxxxxxx
        ReportedBy: grandpachuck187@xxxxxxxxx


When vertically tiling, textures whose height is not a power of 2 (eg, 16, 32,
64, 128, etc) will have a horizontal band of random data when rendered.  This
also seems to affect textures of height 256.  Although ZDoom 1.22 fixes the
original Doom's tutti-frutti problem when tiling textures less than 128 tall,
it only works for the aforementioned power of 2 height textures.  ZDoom 1.23
appears to fix the problem, however, the differences in the rendering engine
may make it difficult to copy the fix from ZDoom 1.23.
