LR 4.1 RC2 problem with previews on 2nd monitor (CPU overload)

I installed RC2 of LR 4.1 and it started to overload my CUP (up to 600% on activity monitor) at the task of generating the preview on second display. Up to LR 4.1 RC1 everything was OK here, now during auto-import photo shoot the second screen does have a problem with preview rendering (no preview is generated well - it simply stretches the small preview with bad quality and the CPU gets overload by far at the same time). My iMac got very hot after some 10 minutes or LR 4.1 RC2 work and I had to quit the LR and revert back to RC1. Prior to going back to RC1 I reproduced the RC2 CPU overload immediately once again after complete shutdown and restart of the system so it was not a single isolated case. I had such a problem for the first time ever - I work with Lightroom everyday since version 1.

Please address this bug in final release, and if necessary I can give more details.

My hardware/Software config:
iMac 27 i7CPU mid 2010 + CinemaDisplay 27, OS X Lion 10.7.3 with all latest updates, Adobe CS 5.5 + Photoshop 6 public beta, camera working via AutoImport of Lightroom (Canon WFT E-2 connected to EOS 1DsIII working in FTP mode).

Please reproduce with Activity Monitor running and capture a "sample" of the Lightroom process.

ok, I installed the RC2 again and was able to reproduce the overload on the preview generation. However it was not every time - some previews were generated fine. This time it was not during auto-import but during switching from one picture into another and this time I was in Develop mode.

I attach the sample text file saved with Activity Monitor running at the time when it was overloading the CPU. The green CPU graph in Activity Monitor was constantly at top values at this time.

I was able to stop this later by switching into another mode and another picture.

Hope this help and if you find anything in it please let me briefly know.

PS: I was not able to attach the text file to directly the my reply and pasting the sample into the reply body is not a good idea so I zipped just the sample txt file and published into my own server with the URL below:
