Black bug when opening files in register

[guilhermepovala]

Hi,

Always when I open register with more than one file, this bug occurs. Can someone help me with that?

Thank you!

Are you running it over SSH by any chance? Or inside of virtual machine.

[guilhermepovala]

No, I'm using in native ubuntu 19.04. I've already tested in ubuntu 16.04 and 18.04.

Modern versions of Ubuntu seem to have some bad interactions with nvidia/opengl. Resize the window usually fixes it.

This is probably a bug in GLUT.

[guilhermepovala]

I'm using the register that comes with minc. This bug occurs in all computers here in the lab.
When the window is resized the black portion becomes normal. But when another interaction with the images is made, the bug comes back.

I thought it could be some missing library, but it seems to be another problem.

does it have NVIDIA GPU?

[guilhermepovala]

Until last week, it doesn't. I installed one yesterday. The bug was happening before and continues after the installation.

[vfonov]

does it use NVIDIA driver ?

[guilhermepovala]

Now, yes.

[vfonov]

it doesn't say which driver it is using

[vfonov]

glxinfo shows this information

[guilhermepovala]

Here is my glxinfo output:

glxinfo.txt

[guilhermepovala]

$ glxinfo | grep OpenGL

[vfonov]

well, it's a mystery.

[guilhermepovala]

Is there any chance it can work using docker?

[gdevenyi]

I have the same bug in 18.04 with intel:

[gdevenyi]

docker with any graphical application is pretty much a no-go, its a mess to feedthrough the X access.

Plus, I have expectation that docker will fix anything.

[vfonov]

we still don't know which version of minc/register that is

[guilhermepovala]

Minc 1.9.17
Register 1.5.0 (built Jul 1 2019) git:HEAD/a391751

[vfonov]

maybe it's a sign to switch to nifti?

[vfonov]

you can try
LIBGL_ALWAYS_INDIRECT=1 register file1.mnc file2.mnc

[guilhermepovala]

Well, using LIBGL_ALWAYS_INDIRECT=1 didn't fix the issue.

Some information that might be helpful:

• When opening a .mnc file as the first one, the bug always happen;
• When a .nii file is the first one, even followed by other .mnc files, it seems that register work normally.

[vfonov]

looks like nifti is the answer
