I let the stove cool down to inspect inside as I notice flame being pull toward the back corner on the right side. There seems to be a small gap that allow some smoke out, bypassing the baffle. The bracket that hold the baffle on the right side was about 1/4'' higher in the back then in the front. It was kinda stuck. I wiggle it and was able to bring it down. Now there is no more visible gap. Not sure if it is the cause of the problem but the fire seems more balance left to right now and the windows does not seems to be getting dirty anymore.
I will report back after a few more fire.
Thanks again for all the tips.
