Priority: medium
Bug ID: 68380
Assignee: [email protected]
Summary: flink race on wayland
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: Other
Status: NEW
Version: git
Component: EGL
Product: Mesa
1. We render stuff using OpenGL
2. eglSwapBuffers - This will call wl_surface_attach, i.e. send the buffer to
server
3. Window resize happens
4. Mesa code does GEM close on all buffers
5. Server receives the buffer and tries to open it by name, but by that moment
the buffer is no more and open fails
Workaround:
1. Do not always close GEM on window resize, close it only if buffer is not
locked
2. In platform_wayland.c:wl_buffer_release if buffer's dimensions don't match
widow's dimensions then the buffer and the GEM must be destroyed
