Potential race conditions in rendering engines #693
Description
There is a bunch of variables that are accessed in a multi-threaded context (rendering) without any protection against race conditions.
For instance:
RTPathOCLRenderEngine::frameTime
RTPathOCLRenderEngine::useFastCamerEditPath
RTPathOCLRenderEngine::syncType
RenderEngine::started
RenderEngine::editMode
RenderEngine::pauseMode
Etc.
Minimal protection, like atomics, should be applied to avoid subtle random errors.
A good approach may be to search for such variables in *thread.cpp files.
