Mesa 17 (Ubuntu 16.04 HWE) breaks the dash's blur (dash and launcher are black)

[Jakub Trybowski]

System: Ubuntu 16.04 32-bit + HWE
Video card: GF 7300GT
Driver: nouveau

I'm testing the latest HWE stack. With Mesa 17 and enabled blur activating the dash results in all transparent elements getting black. Also, the launcher and panel are dark when the windows spread/scale is active.

Disabling the blur or reverting to Mesa 12 solves the problem.

please try 17.1.x from:

ppa:ubuntu-x-swat/updates

[Jakub Trybowski (jakub-trybowski)]

Mesa 17.1 (ppa:ubuntu-x-swat/updates) and 17.2 (ppa:oibaf/graphics-drivers) make no difference.

[Jakub Trybowski (jakub-trybowski)]

Just tried xorg-edgers. The bug remains.

[Timo Aaltonen (tjaalton)]

can you file this upstream?

On 16.04 LTS release, the recent update of mesa (17.0.7) packages, broke VA-API.

I see little to no point in reportinng this problem upstream, as - unfortunately - there are more bugs in Mesa/Nouveau which freeze the entire system. Currently I'm back to the proprietary driver.

[Timo Aaltonen (tjaalton)]

ok, closing the bug then

aditya: don't hijack bugs. I don't have that issue on my system btw
