OpenGL renderer string: Gallium 0.4 on NVA8 Still - I'm glad the crash handler is doing its job nicely for you. If this method returns true - we assume that we can get GL up and running so we need to do a deeper probe and sanity check in there (I guess). To check whether we can in fact initialize this (or not) before we get much further. I guess we should be doing this inside:īool OpenGLHelper: :isVCLOpenGLEna bled() Rtl: :Reference pContext = OpenGLContext: :Create( ) Window aWin = pProvider- >GetX11Window( )

X11WindowPr ovider *pProvider = dynamic_ cast(mrParent. Rtl::Reference X11OpenGLSalGra phicsImpl: :CreateWinConte xt() We can check for this in the GLEW init and return false if we fail (all well and good) - but then that is not actually checked: If( !pFramebuffer & mnFramebufferCount mpPrevFramebuffer = mpLastFramebuffer #2 0x00007ffff68b027f in OpenGLSalGraphicsImpl::CheckOffscreenTexture at /build/libreoffice-slmnDx/libreoffice-5.1.0~rc3/vcl/opengl/gdiimpl.cxx:477

It'd also be great to get a trace from 5.1.1.rc1 (or even 2 coming soon) if possible. it is very unclear how that could be NULL.

Unfortunately the back-trace with symbols (which is great - it looks like calling a virtual / null function somehow) seems rather odd: UpgradeStatus: Upgraded to xenial on (9 days ago) InstallationDate: Installed on (2198 days ago) WORKAROUND: Use 5.3.0~rc3- 0ubuntu1~ xenial1.

I've attached the gdb trace resulting from the crash with debug symbols, following is an except: I'm able to use glxgears and other apps like djv_view with fast rendering. Server glx vendor string: NVIDIA Corporation I noticed that Libreoffice was rendering very slow (I can see each menu option drawn) so I tried using OpenGL rendering, which causes libreoffice to crash immediately on start-up.
