Not sure if this is the right place for a bug report, if not could anyone direct me to the right place please.
Clicking develop module at top right from the Library module opens the photo with film strip and both side bars black empty spaces. Initial few times I had to quit and restart Lightroom but then discovered switching to grid view again and develop keyboard short cut, everything comes back.

As noted before, this is a bug introduced at the macOS level. Through collaboration with Apple, they have made a fix in the later version of the macOS update. So the right thing to do is to update to the more recent version of macOS when possible.
Having said that, Lr team have done our best to workaround this issue for the cases that we can reproduce for macOS 10.11.6. But there is a limit can Lr can do.
This should now work correctly in Lightroom CC2015.10/6.10 or later on macOS Sierra (10.12) or later. Don't hesitate to let us know if you see the issue again on the current macOS, and if you do, what triggers it. Please update your system and let us know if you have any additional issues.
