Flicker/Tearing

[Pramod-Viswanath]

HIi,

I am new to imgui. I am exploring the library with glfw3. Running the demo application on Dell inspiron workstation laptop that has NVIDIA graphics card. When I run the application and drag the demo window, I get tearing and flicker.

What am I missing?

Imgui v1.88 WIP / docking branch, built locally and referred the headers.

Regards,
Pramod.

To clarify: Are you one of the examples unmodified or your own app? Also which rendering backend are you using?

It looks like the backbuffer isn't getting cleared.

I haven't modified any code of examples. Just using it as is. I am using imgui_impl_opengl3.

David, thanks for the hint about back buffer. I was calling glfwSwapBuffers(window); twice in the loop which caused intense flicker nad tearing. Thanks!
