Flickering even on a FrameProfiler's Capture

So… one of the test projects I use for a framework I’m workning on is showing flickering if I have posteffects enabled… but my other test projects show perfectly fine… if I capture a frame the flickering is still happening in the FrameProfiler while looking at a single event of the capture. But if I configure in the connection process “Force Repaint” to “yes”, and “DXGI SyncInterval” to “4”… the flickering dissapears (although the image still shows a little dark).

I’m using GeForce 150MX with the latest driver (460.89 - 12/15/2020) on Windows 10.

Could this be a driver bug?

I uploaded a C++ capture here:
