terminal screen black or blinking in latest unity8 snap

[Victor gonzalez]

STORY: with the latest version of unity8 snap I have a black screen when opening terminal app and the screen blinks if you type something or press mouse buttons

Environment: Zesty

STEPS:

1º Install latest unity8-snap-install(with unity8-session 448)
2º Enter unity8-session snap
3º Open terminal-app

Current result: terminal app window is black
Expected result: should show the terminal app like if it is open in unity7

Status changed to 'Confirmed' because the bug affects multiple users.

the latest version is edge: 16.04 (450) 401MB devmode

:D

[dinamic (dinamic6661)]

the terminal looks ok on 450.. ok in the sense that is how it always been... it's ubuntu-terminal-app snaps running on Xmir (not sure why it doesn't native o_O ). if the terminal app is black try resizing the window, does the trick here.

interesting, taking a screenshot locks unity (attached is the unity8 log if anyone is interested, it's too spammy for me)

[Daniel van Vugt (vanvugt)]

The "black or blinking" is Xmir GLX bug 1510025.

So the real bug here as dinamic points out, is that Xmir is in the snap. It should not be running Xmir and should not come with Xmir.

[Daniel van Vugt (vanvugt)]

Or rather, if Xmir is present in a snap then native apps should default to ignore it and use Mir instead of GLX.
