Makefile for swap-buffer-composite-test.c
I assume "our patches posted to this list for portrait mode and 2048x2048 XV" is at bug#22472. Yes "out patches" are #22470, #22472, #22474. So is this fixed as part of your patchset, Barry? May patch sets do not have a fix for this problem. Barry I can only see left edge and right edge got some tearing. Is that the issue you addressed? I'm using mode 1680x1050 59.9*+ Shuang, You see tearing which is clearly a bug. But its not the problem I was seeing. I see a tear around the middle of the first line. The rest of the screen is tear free.
