- Screenshots with activated PAL emulation do not deliver the expected
  (blurry) result. 

- The Linux/DGA2 code is known to be unstable, especially when
  switching back to window mode under some circumstances.

- The Linux/DGA1 and Linux/VIDMODE fullscreen support may be unstable
  on some systems. Double size/scan does not work currenty.

- The Unix/Gnome port file selector filter does not take care about
  directories which are most probably filtered out and not
  listed. Once the directory is changed within the file selector the
  filter doesn't apply anymore and directories are shown.

- Some basic features of the VDC are missing. In the MS-DOS port you
  have to save the configuration and restart the emulator when
  changing VDC double size mode.

- In the C128 emulation VIC-II and VDC palette can not coexist
  currently in some ports.

- The VIC-II implementation lacks cycle exact sprite support.

- The CBM-II emulation is not fully supported in all ports.

- When loading a snapshot, the monitor break/watchpoints break.
  (at least in xpet)

- The custom TextField widget is buggy and can cause crashes on
  DEC/Alpha machines, and possibly on other systems too.  If you get
  weird X protocol errors or the file selector makes the emulator die
  when you close it, this might be the cause.  In that case, recompile
  with the `--disable-textfield' option.  If it still does not work,
  please tell us.

- Some DEC/Alpha machines crash due to the XAW implementation.  Compile
  VICE with GNOME support `--enable-gnomeui' instead.

- Dithering on monochrome X11 servers is *very* (VERY!) slow.

- When a key which is shifted on the real machine but unshifted on the
  PC or Unix keyboard you are using is pressed, the virtual shift is
  pressed together (i.e. at the same clock cycle) with the main key;
  this could not work with some keyboard routines.  If you have to
  use the function keys, press the (real) shift key manually (e.g. F2
  = Shift + F1, F4 = Shift + F3 and so on); this also works with other
  keys.

- The CBM-II emulator, when the execution bank is set to an open memory
  bank, sets the zeropage and stack access to unmapped, but actually
  existing memory. This is a bug but cannot be avoided with the current
  CPU code architecture.

- When running the burn-in and diagnostics test of the 8296 system disk
  on "xpet -model 8296" a lot of stuff fails.

- Although both are emulated in the xcbm2 emulator, switching between
  C510 and C6x0/7x0 is not possible at runtime. Use command line option
  "xcbm -model 510".

- Dual disk drive 2040/3040 support (DOS1, 670 blocks free) is not working 

- In the C510 emulation the VIC-II timing is not exact, i.e. the
  stopping of the CPU during bad lines is wrong.
