At present, it is not possible. Track an issue https://github.com/DevExpress/testcafe/issues/1520 to be aware about progress.
Hi @maqpratika
Starting with
0.20.4version, TestCafe uses a build-in browser functionality for making screenshots (only forChromeandFirefox). It allows TestCafe to prevent all platform-specific problems with screenshots.Try this version and tell us about your results.
This issue must be fixed by https://github.com/DevExpress/testcafe/pull/2492. I’ll notify you when a build with the fix will be published on NPM. Feel free to try the fixed build and reopen the issue if the problem isn’t solved in your environment.
@AlexanderMoskovkin Thank you! will have a look and return with feedback
