The blur operations were clamping the filter size to 1, which prevents
no-op blur nodes. Further any value < 1 would also be ignored and in
many combinations the filter scale setting ("Size") would only work in
integer steps.
Now most blur settings will work with smooth Size value scaling as well,
meaning you can choose a reasonably large filter size (e.g. 10) and then
use the Size factor to scale the actual blur radius smoothly.
Note that non-integer filter sizes also depend on the filter type
selected in the Blur node, e.g. "Flat" filtering will still ignore
smooth filter sizes. Gaussian filters work best for this purpose.
Issue was caused by too hight value used for size,
which came from infinite Z-buffer point.
Solved the crash by clamoing maximal gaussian table
radius to 30K, which seems to be reasonable.
only visible when doing large size blurs.
also solved the catcom/mitch filter that didn't work at low/medium quality
PS never use BokehBlur Gausian filter as it is 99%+ identicat as non bokeh <= top for sergey- :)
