Re: [Mesa3d-dev] [Bug 27628] glxgears prints bogus swap interval information

[Mario K. <mar...@tu...>]

Hmm. The patch inits mesa's local cached copy of swap_interval to  
zero. The DRI2CreateDrawable() function inside the xserver's xserver/ 
hw/xfree86/dri2/dri2.c implementation inits its own copy of  
swap_interval to 1, at least in the DRI2 patch series of Jesse and  
mine that is supposed be pulled of the next x-server release.

So until client code calls glXSetSwapIntervalMESA() or  
glXSetSwapIntervalSGI() the first time, the returned value will not  
match the true setting.

Either we need to match the defaults, or propagate the mesa setting  
to the server at drawable creation time, or query the server's  
setting to init mesa's copy.

thanks,
