[Kasireddy, Vivek] Which UI module (and Host environment) are you testing with? gtk? egl-headless? Could you please provide more details about the environment and the use-case?

[Kasireddy, Vivek] IIUC, contexts can only be bound to one thread at a time. So you either need to release the context in the other thread (eglMakeCurrent(NULL, NULL) before making it current in your current thread or create a shared context between both the threads to be able to share textures.
