[Touch-packages] [Bug 1611363] Re: vim.gtk3 crashes frequently with SIGSEGV in ffi_call_unix64()

[Gilles Schintgen]

I forgot to add a reference to vim's bugtracker on github:
https://github.com/vim/vim/issues/851
but as I said before, "libunity-gtk3-parser.so.0" seems to make it 
Ubuntu-specific.

  vim.gtk3 crashes frequently with SIGSEGV in ffi_call_unix64()

Status in vim package in Ubuntu:
  New

Bug description:
  Hi, vim-gtk3 crashes so often on my system that it's borderline unusable.
  My system is a clean install of Ubuntu 16.04. I also (temporarily) renamed my 
customized ~/.vimrc and ~/.vim. My system is up-to-date as of today 
(2016-08-09); installed vim-gtk3 is 2:7.4.1689-3ubuntu1.1.

  The crash happens only (but very frequently, not always) when I launch
  gvim, either by calling it from a shell or by double-clicking a file
  in Nautilus. Note that the crash is independent of whether I'm opening
  a file or not. (At least I tried both variations from the terminal.)

  There's also a report on vim's bugtracker, but since unity appears in
  the backtrace, the consensus is that it's probably Ubuntu-specific.

[Touch-packages] [Bug 1072206] Re: [nvidia] Window content is black or transparent

[Gilles Schintgen]

Hi,
I wasn't following this bug until today when I thought enough is enough. (It's 
been annoying me for quite some time)

I'm skeptical of the "fix released" status, since I am *still*
experiencing the described behaviour: black or transparent windows.

Ubuntu 14.04
compiz 1:0.9.11.3+14.04.20150313-0ubuntu1
nvidia-304-updates 304.125-0ubuntu0.0.2

Thanks to everybody for investigating this non-critical but very
annoying bug!

Bug description:
  [ Impact ]

  With nVidia hardware from time to time window content is rendered
  black or transparent.  The problem manifests more frequently as
  session uptime increases.

  Apparently the problem was caused by textures being cached and not
  freed, resulting in memory exhaustion conditions.  It turns out the
  texture caching is unnecessary anyway.

  [ Test Case ]

  Verification requires an nVidia GPU with proprietary drivers.  The
  problem can not be reproduced at will, only after some time (depending
  on resident GPU memory and usage) and even then only randomly and
  unreliably.

  [ Regression Potential ]

  It is unlikely this change has the potential to introduce new
  regressions.

  [ Other Info ]

  Fix was cherry-picked from the Ubuntu "Vivid Vervet" dev relase where
  it has been in use for some weeks without problem.
