As attached here, in one of your test runs, failure is caused due to capture of distorted image. ![image2](https://private-user-images.githubusercontent.com/94159358/363084865-5744cb82-24da-45c3-a5d9-e88b7864bae3.png?jwt=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.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

I have further stabilised the test by increasing the delay before taking the screenshot and I ran it 100 times on the same machine where it failed earlier and now all the runs are passed. Latest Mach5 links are attached in the bug.
