I've had this crash multiple times in the past few days with mesa 20.0.8, always when interacting with UI elements (menu button, search bar). A pre-condition may be to play a video with DMABUF?

• Other libEGL_mesa crashes.
  Some mention GetBufferAge (bp-d1d20049-6bcb-436d-8a1e-713470200528), __driDriverGetExtensions_i915 (bp-8ab61a7b-0f44-4cbd-bbf2-4c7cf0200528) or __driDriverGetExtensions_virtio_gpu (bp-1eb14fe7-cdf3-4ab0-9a98-f48ad0200527).
  There is one that contains wl_proxy_create_wrapper.
  • Other crashes that contain wl_proxy_create_wrapper

Please post your other crash report IDs. Have you changed gfx.webrender.max-partial-present-rects? Can you fix these crashes by resetting it to 0 or by disabling dmabuf prefs?

gfx.webrender.max-partial-present-rects was not changed and is set to 0, I will try disabling dmabuf.

The bug has not happened again so, it was probably fixed by chance in FF or mesa...
