Applications block on eglswapBuffers due to buggy mesa version

[Mohamed Sharaf-El-Deen]

[Impact]
The mesa version that is available after installing packages has a bug that leads to wayland applications blocking on eglSwapBuffers if egl swap interval is set to Zero.

Ubuntu version: 18.04 LTS
Currently available mesa version for installation: 18.0.0~rc5

Versions where the bug is fixed:
17.3.8, 18.0.2, 18.1.0, or later

[Test case]
More details about the bug, how to reproduce it and the right mesa versions to use in here:
https://bugs.freedesktop.org/show_bug.cgi?id=106719

Would be so good if it is possible to provide one of the mesa versions where the problem does not exist as a package for installation.

Thanks

[Regression potential]
none known, and we're SRUing 18.0.5 which is the last one of the series so shouldn't have regressions caused by earlier bugfixes..
