*** This bug has been marked as a duplicate of bug 55998 *** according to https://bugs.freedesktop.org/show_bug.cgi?id=55998#c29 git bisect bad e1cb50b15dbb75d1ba0fe184d05be7d302b058ee is the first bad commit commit e1cb50b15dbb75d1ba0fe184d05be7d302b058ee Author: Robert Bragg <robert@linux.intel.com> Date: Tue Sep 18 16:10:03 2012 +0100 SwapBuffersRegionNOK: invert rectangles on y axis The EGL_NOK_swap_region2 spec states that the rectangles are specified with a bottom-left origin within a surface coordinate space also with a bottom left origin, so this patch ensures the rectangles are flipped before passing them on to dri2_copy_region. Fixes piglit's egl-nok-swap-region test. Tested-by: Matt Turner <mattst88@gmail.com> (cherry picked from commit 0a523a8820e8a2549ac1c7887eb1892b228af44b) this commit introduced regression. KWin uses EGL_NV_post_sub_buffer to do partial updates. But it looks like dri2_swap_buffers_region(), which this commit changed, is called by both eglSwapBuffersRegionNOK() and eglPostSubBufferNV(). So this commit fixed one entry point and broke the other. Created attachment 69634 [details] [review] egl_dri2/x11: Fix eglPostSubBufferNV() This patch should fix the problem.

Reviewed-by: Ian Romanick <ian.d.romanick@intel.com> it works too :) thanks for fix Fixed by commit f42518962a08ce927e4ddd233d19d2661e135834. |
