Title:
Mir Mesa EGL platform leaks memory with every frame
Status in Mir:
Fix Released
Status in mesa package in Ubuntu:
Fix Released
Bug description:
The Mir Mesa EGL platform leaks memory with every frame. This is the
result of incorrect handling of the buffer objects we create from the
incoming Mir buffers.
The problem is exhibited in the attached 'massif.out.leak' file. An
excerpt from the result of ms_print for this file:

I have attached a patch (fix-mir-mesa-egl-gbm-bo-leak.diff) to get
some wider review before creating a final patch for the ubuntu
package. With this patch the leak is fixed as shown in the attached
'massif.out.fixed' file:
