To chime in, the jvm (1.8.60) crashes on debian jessie (virtualbox)
when using the opengl2 rendering backend (vtk 6.3.0rc1 and rc2) and
the swtComponent. The old OpenGL works fine.<br>
When not using virtualbox's 3d accelleration the window wont even
open. When activating the 3d accelleration you get a window but as
soon as you add some actors and call update it crashes (some of the
time).<br>
Also the jvm crashes when running everything on "real" hardware
(Intel HD Graphics 4600) instead of a virtual machine. <br>
Unfortunately i cannot access the logs right now (vacation) if this
still is an issue after, i happily provide any logs you desire :-)<br>
Just wanted to let you know, keep up the good work!<br>
<br>
<br>
i also have segfaults with the opengl2 backend on linux (debian
jessie) running on virtualbox.<br>

<blockquote cite="mid:55EB4345.2070508@gmail.com" type="cite">I keep
getting segfaults when using vtk.sample.VTKCanvas with OpenGL2
backend in 6.3.0.rc2. This does not happen with 6.2.0 + OpenGL2,
nor with the standard OpenGL backend. I use ubuntu 14.04 and
compile with gcc 4.9.2 and jdk1.8.0_60.
<br>
<br>
On my laptop, the segfaults are 100 reproducible with mesa library
- some lines from glxinfo:
<br>
<br>
<br>
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile
<br>
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.3
<br>
OpenGL core profile shading language version string: 3.30
<br>
<br>
<br>
When I use the high performance card (fglrx drivers, Radeon HD
8790M) the segfaults sometimes happen, sometimes not. Lines from
glxinfo:
<br>
<br>
<br>
OpenGL vendor string: Advanced Micro Devices, Inc.
<br>
OpenGL renderer string: AMD Radeon HD 8790M
<br>
OpenGL core profile version string: 4.3.13374 Core Profile Context
15.20.1013
<br>
OpenGL core profile shading language version string: 4.40
<br>
<br>
<br>
I have attached a simplified java code based on VTKCanvas - In my
experience this one segfaults always, both with mesa, and with
Radeon drivers. I get the following line before vtk dies:
<br>
<br>
<br>
ERROR: In

And this is the top of the stack reported by the dying Java VM

<br>
<br>
<br>
It seems that this is a problem specific to 6.3.0.rc2 with
OpenGL2. I could not reproduce it for 6.2.0, nor when using OpenGL
backend. Do you know any reason why this could happen? I will be
happy to provide more information and help to solve this.
<br>

Cheers,
