@mrserb Since the current test fix works on other platforms (windows, mac) other than linux, can the other platforms be removed and the test be problemlisted only on linux platform until the product bug is fixed on linux then? Additionally the test was failing on Mac-ARM due to color mismatch that was fixed by adding tolerance.
