Hi
If you set 'pretrace_start' to 0.01 and forget to set 'pretrace_end' at
the radiosity definition the preview calculation will be repeated many
times before proper pixel rendering will start.
example:
radiosity {
pretrace_start 0.01
// pretrace_end 0.01 // preview error when you forget this parameter
}
btw. PovRay v3.62 preview calculation is working as expected!
Using 640*480 resolution and set pretrace_start to 0.01 it displays a
preview picture with interpolated pixel colors.

Confirmed. Thanks for the report.
