Sky broken in Linux (Integrated Card)

When using Stellar Sky I always get OpenGL errors and a broken sky: either RGB stripes or colored tv static (https://imgur.com/a/WEDiJ). I tried two different minecraft (and forge and Stellar...) versions with similar results.
The errors are repeating and mostly of this shape:

[main/ERROR]: ########## GL ERROR ##########
[main/ERROR]: @ Post render
[main/ERROR]: 1286: Invalid framebuffer operation

Error logs: https://pastebin.com/uc7Tf0Cq and https://pastebin.com/UCq3Cbn4

Does anyone know about this issue?

commented

Wow, this looks both frustrating and splendid.
I'll investigate this one on the highest priority. I guess it could be a driver bug.

commented

I think float16 format is unsupported in your platform, even if the flag says otherwise.
I'll try to fix this.

commented

Before trying, would you please update your graphic drivers? This could just be a bug.
EDIT: Also try with the latest version.

commented

It looks like I'm using the latest driver.... Have to check the float16 thing more in detail
You mean I should try with the latest StellarSky Version?
Why do you think float16 is unsupported? I'm not really into graphics drivers and don't know where to gather the information.

commented

Also the latest (april) version still looks the same for me ๐Ÿ˜‡

commented

It's written on the log - float16 not supported.
Would you post the latest log? I want to know if the situation changed or not.

commented

it still says so....

Also I found out I am using Mesa 10.1.3, OpenGL 3.3 and GLX 1.4
(glxinfo: OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.3)
I don't know if it may be intereseting: I'm using Ubuntu 14.04 on a i7-4600U with Intel HD 4600

commented

Sorry for being late, but...
Closer look on this one gives me impression of one of the hardest bug to beat : a driver bug.
May I ask, still no updates available on the driver?

commented

Sorry for being late, but...

Never mind ๐Ÿ˜„

I'll check for driver updates and tell you.

commented

How's it like on the latest beta version? Please check it

commented

So you don't have dedicated graphics card, but only integrated card?

commented

Still getting the error (in console). But I don't get the fuzzy thing any more ๐Ÿค”: Now it's just plain black.
Also I did some searching and found someone who's had a very similar issue with vanilla minecraft, because other applications were using hardware acceleration...

commented

I am starting to believe it has something to do with using an older OS... I will try it on a newer one

commented

Do you have your own dedicated graphics card? If you have, then try to use that one.
Probably Minecraft is running software emulation in your case, which is slow and unreliable.

commented

It's an Intel HD 4600 (?).
And I assume it's hardware accelerated, but I haven't found the settings for it.

commented

This is certainly a driver bug. I checked that the framebuffer is complete, yet it gives 1286: Invalid framebuffer operation error - which should only happen when the framebuffer is incomplete.

commented

But I'll check if it's this case - I'm going to request you to test one or two more versions in a few days, is it okay?

commented

nope ๐Ÿ˜‡
works pretty well with minecraft. Without fancy shaders, obviously ๐Ÿ˜’

commented

Would you post current log?

commented

sure
if you know some way to debug it to get more detailed info on the error, I could do it (I currently have no idea of graphics cards)
