Realtime display modes go into an unending update loop

had an issue reported with my renderer’s realtime display mode going into some kind of update loop; traced it down to being caused by some combination of a) blocks, b) edge softening, and c) textures

reduced the test case further and was able to repro using cycles raytraced (and my renderer completely uninstalled); here is a video recorded using windows 8.13.24317.13001, where the sequence of events shown is:

  1. open file, start raytraced viewport, all is ok
  2. change material roughness (could be anything, or a texture param)
  3. the raytraced viewport starts going into a loop of updates
  4. restart raytraced viewport, all is ok again
  5. repeat steps 2-3

and here is the file:
