I'm currently on lightroom version: CC 2015.10.1 [ 1117303 ] and my system is configured with an i7 6700k and an AMD R9 390(latest driver). Beginning with the last update, and continuing with the most recent update I experience frequent crashes when Im using my gpu and attempt to switch to the develop module. Disabling the graphics processor returns me to stability, however developing is a great deal slower without it. I've spoken with a few other users with AMD GPUs who are experiencing similar issues. I understand this is probably a bug and we'll just have to wait for an update, but does anyone have any suggestions on further troubleshooting or workarounds I could attempt. I have several jobs to work through and need the extra boost.
According to this help article, disabling the GPU will stop the crashes, as will rolling back to a previous driver version: Crash Camera Raw or Lightroom
Please add your me-too vote and details of your configuration to this bug report in the official Adobe feedback forum: Lightroom: Crashing with GPU acceleration on (AMD Radeon driver 17.4.4) | Photoshop Family Customer Community . That will make it a little more likely Adobe will prioritize the fix, and you'll be notified when the status changes.
