Hello @silkdemon,

This issue is related to ChromeDriver and is not specific to TestCafe. It was also reported in the ChromeDriver issue tracker.

As a workaround, you can use the --headless=old flag to run Chrome in the old headless mode or hide the window (set the position off-screen with the --window-position=-2400,-2400 flag for this purpose).

npx testcafe 'chrome --headless=old' .\PATH_TO_TEST_FILE
npx testcafe 'chrome "--window-position=-2400,-2400"' .\PATH_TO_TEST_FILE
