Lightroom : (really) slow, artefacts on image when applying modification

Since last update (applied yesterday), Lightroom is really sluggish for whatever operation I try. When switching from library to development mode, it takes several seconds for the preview to adapt, i.e. the original picture is displayed for a long time before the effects of my settings are visible.

When I manipulate the image in development mode, the preview is not smooth anymore. I got some black areas or lines flickering on the picture as I move the cursors, or reframe the picture, for example. It is really annoying, and almost gave me headaches. I had to stop working on my pictures for tonight because of this !!

When browsing collections in library mode, the previews take a lot more time to be accurate and updated to last settings.

I didn't  have such issues with the previous version, which ran smoothly on my MBP 2011 with i7, 8Go RAM, 1To SSD, AMD HD6750M.

Please get us a patch for this, or tell me how to revert to old version !!

I have the same problem with my MPB that has the same graphics cards. I'm wondering if its specific to it. I have GPU acceleration turned on.

Yes, the GPU acceleration is ON (always been like that).
