Thanks for your prompt reply.
I tried it twice, but LR also crashes upon unchecking the box.
Then you need to start looking at the hardware in your computer. Something isn't right with some part of the hardware.
I didn't have the opportunity to test your solution yesterday. Today I used LR normally for about 2 hours working normally on my photographs. Everything works fine now. Indeed the box for using the GPU is unchecked after the change in the LR preference file.
For the full picture: my pc has an i7-4790 processor and "simple" AMD Radeon R7-240 graphics. Before the early August 2015 updates LR worked fine with GPU on. But I don't notice a worsening in performance now with GPU off in LR.
I have been having exactly those same symptoms. With an AMD Radeon 6700, 3.5Ghz quad core i7, 16GB RAM, Windows 7 Pro. Disabling the GPU seems to have solved it for me. As a test, the GPU acceleration was re-enabled and the symptoms almost immediately reoccurred.
W M Thank for posting the question ! And thank you ~Akash for providing a clear solution which, worked in this case.
