5. _K_n_o_w_n__P_r_o_b_l_e_m_s__a_n_d__W_o_r_k_a_r_o_u_n_d_s
+o Silicon Graphics has no plans to implement a multi-
threaded version of the X server.
+o _x_s_t_d_c_m_a_p does not work properly, nor do the colormap
utilities in _l_i_b_X_m_u. The X server creates the standard
colormap properties by default at startup. They work
properly if not accessed through _l_i_b_X_m_u.
+o In the search pane of the Insight application, any
search in the Xt library will come up saying
XLib_WinSys, rather than referring to Xt. Similarly,
searches for the Xlib library come up saying XLib_PG.
+o On older graphics platforms, X and OpenGL do not
coordinate swapping a double-buffered window properly
if swapping buffers through the X server. Thus, when
rendering X and OpenGL to the same window, it is safest
if buffer swapping is handled using the glXSwapBuffers
call.
+o When running OpenGL applications that use indirect
rendering, it is normal for more than one instance of
Xsgi, the SGI X server, to show up under 'ps'. They
represent multiple threads of the X server, used to
implement indirect rendering.
+o The X server does not yet support the large request
mechanism. Protocol requests are limited to 64K words
(262,144 bytes) in length. This applies to the core X
protocol as well as to extension protocols such as PEX.
+o The function _X_v_c_L_o_a_d_V_i_d_e_o_F_o_r_m_a_t_C_o_m_b_i_n_a_t_i_o_n does not
return a proper status code from servers running on
InfiniteReality graphics platforms. This will be fixed
in a subsequent release of software.
