Known bugs and issues
=====================
The Known Issues section contains those items that are big and
important but are not currently actively worked on, because they need
a lot of effort or there is no solution yet for them. For a more detailed
list of issues and bugs please check the list in `issue tracker`_.
* **Display bugs:** Mayavi, and VTK, heavily use hardware rendering, as a
result are very sensitive to hardware rendering bugs. Common
issues include surfaces showing up as black instead of colored
(mostly on windows or in virtual machines, I believe), z-ordering
bugs where hidden triangles are displayed in front of the triangles
that should hide them (a common bug on Linux with intel graphics
cards), or the rendering windows becoming grey when the focus is
moved out (often seen on Linux, when compiz is enabled). The
solution is most often simply to turn off hardware rendering in the
system settings (turn off compiz under Linux) or change
graphics-card drivers (under Linux, try switching between the open
source one, and the proprietary one).
* **Qt 5:** Mayavi is built on top of the traitsui and pyface gui libraries. Thus
support for Qt 5 is linked to these gui libraries supporting Qt 5.
* **wxPython 3:** Similar to the Qt 5 issue support for wxPython 3 is linked with
the necessary support arriving in the stable releases of the gui libraries.
