Just to be sure we are on the same line, let's me do a summary.
PCSX2 does the following bad pattern
1/ no call to XInitThread
2/ XGetGeometry to get the size of the surface
3/ glDrawArray into the default framebuffer 0 (the window, I'm not sure how to
=> which seem to call DRI2GetBuffersWithFormat under the hood. I guess to
associated buffer of the window.
So far it was (kind of) working fine because PCSX2 does tons of PBO transfer.
was mostly synchronous.
This series removes the (useless) PBO transfer synchronization. So now glthread
asynchronous and the above bad pattern crash as expected.
I didn't add any libX11 API call on the patches. And I don't think we can
remvove the DRI stuff.
Hum, I don't know what will be the impact on the perf but potentially we can
force a synchronization
when there is a draw to framebuffer 0.
