Recently there are RBD 8.5 and 9.0 customers experiencing the BuildDescriptor lost problem when trying to debug/generate EGL program.
To solve this problem, they have to perform project-clean action to bring back the BuildDescriptor for use.
Next time when you restart RBD or Windows, the information is lost again.
This problem was not occurred in RBD 7.5 or 8.0.
Did someone also experience this problem ?
