[MC-14646] Cairo-dock displayed over window

Cairo-dock, the graphical shell I use on the concerned computer is shown over the window while playing on the snapshot, when Minecraft is in focus, which obscures the hotbar, and everything on the lower window if Minecraft is maximised.

This did not occur in 1.5.1 (As you can see in the third screenshot. The same is also true in 1.5.2), Where Cairo-dock is correctly hidden behind the game window when the Minecraft window is over it, this is also true in fullscreen.

LWJGL is the same on both versions, as you can see in the second two screenshots, so this is not the issue, as has been previously suggested.

Steps to Reproduce:
1. Start launcher (new dev launcher, not old) by locating it and right clicking, selecting Oracle Java.
2. Select relevant snapshot.
3. click 'Play'.
4. Maximise window if not already (but not F11 fullscreen, the problem does not occur then).
5. The issue becomes apparent: exactly as it appears in the screenshot of the snapshot, cairo-dock is shown over the lower part of the game, when the game is in focus, and the window area is over the dock.

To summarise
Torabi sums it up very well (far better than I can, at any rate):

So, to summarize: The Minecraft window should cover (be on top of) the dock when the Minecraft window has focus. This is the behavior it had in 1.5.1.
The problem being experienced is that the dock is always on top of the Minecraft window, regardless of focus.

Screenshots

1. (2013-04-25 18_27_27) Screenshot In snapshot with issue
2. (2013-04-25 20_31_19) Screenshot showing the version of LWJGL for the snapshot
3. (2013-04-25 20_33_01) Screenshot showing version of LWJGL in 1.5.1, and that the issue does not occur in 1.5.1

Edited to clarify many points, thanks, Torabi

Not sure what we can do about this. Seems to me that LWJGL must somehow know the limits until where it can expand on linux.

This is nothing we can solve. Please report to LWJGL. https://github.com/LWJGL/lwjgl/issues

I assumed the used version of LWJGL is the same, but which is actually used by the snapshot?

Alicja Preocanin 2013-04-25T19:26:11Z

Version of LWJGL used on both my copies of 1.5.1 minecraft and the snapshot is 2.9.0 (confirmed with console on both, I can provide screenshots if it's really necessary), same issue still occurs, so this issue is /not/ invalid, and it's definitely not nothing you can solve.

Alicja Preocanin 2013-04-25T19:41:22Z

Attached screenshots, you may noticed that the snapshot minecraft window is not in focus, but I can assure you that the issue still exists when it is, and I can prove this too if you wish...

Also, I can appreciate that you have to deal with invalid issues on a daily basis, but you really shouldn't dismiss something such as this out of hand.

I notice that the issue clone I created has been trashed, is anyone prepared to offer an explanation for that, or why this issue is being disregarded?

The clone function is not an appropriate substitute for having an issue reopened.

Alicja Preocanin 2013-04-28T21:00:46Z

I added evidence that further substantiates the issue, and which proves that LWJGL is not the problem, but yet it has not been reopened? in those circumstances, it may not be appropriate, but it's the only option that I could see.

Alicja Preocanin 2013-05-27T09:54:05Z

How should I go about getting this reopened, or will I just have to go and create a new account and resubmit a modified one just to be listened to?

Torabi 2013-05-28T15:31:19Z

What good would either of those things do, when Grum has determined that it's something they can't fix? You're asking the impossible, what do you expect to happen? Magic?

Alicja Preocanin 2013-05-28T15:37:11Z

Eh? I've added further screenshots demonstrating that their assumption about the root of the problem is incorrect, so no, I am not asking the impossible, as you would see if you had bothered to look at them.

Seems to me that korikisulda has a point here, this should be reopened until Mojang can explain why it did/does work in 1.5.1 with the same LWJGL version. (It still could be LWJGL-issue, but doesn't look so with the info shown.)

korikisulda: Seems you're claiming this:
Minecraft 1.5.1 with LWJGL 2.9.0 works ok.
Minecraft snapshot 13w17a with the same LWJGL 2.9.0 works bad.

You might want to clarify the issue description a bit; the first minutes of reading this issue I was also in the impression that your claim is invalid... Each additional comment is not clear by itself; only after I read snippets from here and there and looked that screenshots I was able to get the full idea what you have been saying. (Or well, I assume I get it now.)

EDIT: especially the part of happening also on another LWJGL game seems to point towards LWJGL (EDIT2: or that both games happen to use it incorrectly), so it helps a ton if you can emphasize/clarify the info that points towards Minecraft.
Also, might be good to assure that your Linux software didn't change in between; LWJGL might have worked with one version and not with the next..

Torabi 2013-05-28T17:14:14Z

Perhaps you should attach a screenshot showing how 1.5.1 looks when maximized on your system. Are you saying that it covers over the dock, or that it doesn't extend below the dock? Grum's response indicates that he interpreted it as being the latter, but your description suggests the former.

Alicja Preocanin 2013-05-28T17:16:53Z

No, actually, the dock ends up over the window when it's in focus, but thanks, I'll edit it to make it more clear

bugi74 2013-05-28T17:19:23Z

An example of the ambiguity, right from the latest comment: "the dock ends up over the window when it's in focus". I think you mean the dock gets over the minecraft window when the dock is in focus, but when minecraft is in focus, the dock will not be over it?

Alicja Preocanin 2013-05-28T17:26:41Z

No, the dock goes over when the minecraft windows is in focus, that is the issue

Alicja Preocanin 2013-05-28T17:28:13Z

Clarified that point too

bugi74 2013-05-28T17:31:01Z

Oops, that was my bad; I was meaning version 1.5.1 in my last comment, and you were apparently meaning the latest version. Well, the description is now clearer, and at least I can now easily understand the problem and I would not blame LWJGL first after reading it.

Alicja Preocanin 2013-05-28T17:33:09Z

Well, thanks for the help, hopefully they'll consider looking at it again 😉

Torabi 2013-05-28T17:37:18Z

But what did it do in 1.5.1? You've described the problem, but not the previous/desired behavior. How are they supposed to figure out why it worked before, if they don't even know what "worked" means in this instance? Did the Minecraft window cover over the dock, or did it just not extend into the dock's area? Does it do the same thing as a window as it does fullscreen?

If you drag the Minecraft window over the dock area, what does it do in 1.5.1, and what does it do in the snapshot?
If you fullscreen Minecraft, what does it do in 1.5.1?

bugi74 2013-05-28T18:02:06Z

korikisulda, refer to screenshots by their names, not by order, as the order may change (especially if new screenshots are added).

Alicja Preocanin 2013-05-28T18:06:50Z

Added the dates from the screenshot filename under the screenshot header

Torabi 2013-05-28T18:08:10Z

So this is actually a window layering/stacking/z-order issue, and not a bounds/fullscreen issue. That may be something Mojang could actually control.

So, to summarize: The Minecraft window should cover (be on top of) the dock when the Minecraft window has focus. This is the behavior it had in 1.5.1.
The problem being experienced is that the dock is always on top of the Minecraft window, regardless of focus.

Alicja Preocanin 2013-05-28T18:12:27Z

That sums it up perfectly, and now the issue is vaguely presentable, thanks so much Torabi, you really should be a mod here.

Torabi 2013-05-30T16:53:13Z

One more question: what about the launcher window? If you move that down so that it overlaps with the dock, which is on top?

The old launcher (and the game itself, up to 1.5.1) uses javaw. The new one is a native application, and I've read that it launches the game client with java. This may not seem like a big difference, and theoretically, it shouldn't be – but it might have some effect on window layering on some systems.
