[X2Go-Dev] Bug#205: Some comments on this

In nxagent-3.5.0-8 NoMachine has tweaked the version number of nxagent to work better with cairo. So doing this is not completely unusual for NX...

In nx-X11/programs/Xserver/hw/ nxagent/Init.c you can find these lines:

/*

• Avoid slowness due to buggy_repeat workaround
• in libcairo versions >= 1.10. */

SetVendorRelease(70000000);

And in the CHANGELOG:

nxagent-3.5.0-8

• Fixed TR01J02646. Performance issues with cairo version 1.12.

However, the current cairo code contains this (http://cgit.freedesktop.org/cairo/tree/src/cairo-xlib-display.c around line 300):

if (VendorRelease (dpy) >= 60700000) { if (VendorRelease (dpy) < 70000000) display->buggy_repeat = TRUE; }

As NX is presenting itself as 70000000 the condition is false already and changing the version to 70100000 would not change the cairo behaviour here.

BTW: Xorg 6.9 and 7.0 are the same code. 7.0 has just been restructured completely and adapted to automake.
