[Regression] Hideous low-res icon when using the HUD with autohide enabled.

Bug Description

[Test Case]
1. Set Launcher autohide to ON
2. Open and focus any application with a custom high-res icon (e.g. firefox)
3. Open the HUD
-> Verify that the application icon displayed alongside the HUD looks normally smooth

(Might be additionally verified by performing the same steps but for a custom, non-standard Launcher icon size)

[Regression Potential]
Visual regression potential related to the HUD.

Original description:

Regression of bug 931406.

Ever since the update to unity 5.14.0-0ubuntu1 the program icon that displays (where the BFB usually is) has gotten really jagged and gross looking. With autohide OFF, the icon displays properly. With autohide ON, the issue appears.

Can't confirm here, but the screenshot is difficult to deny.

I found out that if I have autohide off then the icon is fine. With autohide on it becomes ugly.

Yes its reproduce able with autohide.

Looks like GL_TEXTURE_MAG_FILTER is set to GL_NEAREST instead of GL_LINEAR.

@Chauncellor which graphics driver are you using?

Intel all the way, baby!
