Is this the issue in KDE that when I start a game I have to toggle compositing a couple of times to get it rendering? On 6 Oct 2014 07:39, "Chris Wilson" chris@chris-wilson.co.uk wrote:

I was looking at a bug report today of intel/ati prime and noticed a number of sna_share_pixmap_backing() failures (called from DRI2UpdatePrime). These were failing as the request was for the scanout buffer (which is tiled and so we refuse to share it, and since it is already on the scanout we refuse to change tiling).
But looking at radeon_dri2_copy_region2(), if DRI2UpdatePrime() fails, the copy is aborted and the update lost. If the copy is made to the normal window drawable is that enough for it to be propagated back through damage tracking?
Have you asked the reporter of that bug to test your patch?
They didn't notice the issue, presumably because it only happens quite early in the DE startup. However, I do remember Dave mentioning what seemed to be a similar issue: a peristent blank window. Hence the inquisitive nature of the patch. -Chris
