The subject pretty says anything.
From simple emulators running atop of sdl to more complex games, the only way to stop them to “tear”, usually with a single line in the top quarter of the screen, is to completely disable the composite extension from xorg.conf.
NO MATTER if i use a compositing WM or not.
NO MATTER if i use a multihead or a single head setup.
Is this expected?
I tested the issue on two systems, different Motherboard, but same card: 9800GT, driven by 331.38 drivers.
I can’t be sure about it, but i don’t remember to have seen this with previous drivers, (nor i have the time needed to test for regressions, sorry).
By now i start the problematic apps on a separate X screen as a workaround.
