If i introduce overridden empty paint() and update(), method i see that only in Linux CI machine it reached a state where nothing was drawn. This happened 1/20 times. Then went through https://www.oracle.com/java/technologies/painting.html which talks about system-triggered painting and app-triggered painting. After adding logs i see that we hit overridden paint method whenever there is resize of frame. Since we are updating the frame using drawImage in a loop, we are not hitting the system triggered paint() on resize with after we call frame.setSize(). I added Thread.yield() after frame.setSize(), but it dooesn't work all the time and it is captured in its doc. So i added robot.waitForIdle after frame.setSize() to make sure that we finish system triggered resize event and then continue drawing image on the frame.
