quick hack (878 bytes, text/plain)
2014-09-16 15:13 UTC, Massimo

Description Massimo 2014-09-16 15:13:35 UTC
Created attachment 106374 [details]
quick hack

It seems that the xlib surface drawable containing the group rendering
has not yet received the content from the shared memory when its content
is copied (XCopyArea) to the destination. The attached quick hack calls
_cairo_xlib_surface_put_shm and it fixes

pthread-same-text and pthread-similar .xlib-fallback.rgb24

BTW at src/cairo-xlib-core-compositor.c line 452 :
it says that when the destination is a Window the GC should be changed
to include ClipByChildren, but few lines below (line 498) ClipByChildren
is set when source does not owns a Pixmap, and it is set after XCopyArea
has been called.
