Hi @jobitmathew, probably more people watch the mailing list than the github issues.

I think "Dropped frames" is being reported by the Blackmagic driver / decklinksrc. It means your computer isn't processing the frames fast enough so it's skipping some frames (not delivering them to stb-tester). That shouldn't affect your test -- stb-tester will just process the next frame that is available.

The test failure is probably unrelated to the "dropped frames" warnings. You didn't show us the output of the test when it failed. stbt run should also save a screenshot when the test failed.
