What a waste of space! This new version is utter rubbish. There are so many bugs it is impossible to list them all. I have the latest drivers for my video card but I have to turn off the gpu. The screen flickers when image adjustments are made, If using the erase brush is being used the screen flickers and switches back to the add brush. It is nigh on impossible to use the radial filter (one of my favourite tools by the way). I have had to go back to using Lightroom 5.7. Please, please, please sort these issues out quickly. This is not the sort of thing you would expect from such a flagship image manipulation company. EMBARASSING!
