GCC 4.8 and TeXworks (LaTeX editor) zooming and cpu usage.

[Fabian Inostroza <totoxahcp@xxxxxxxxx>]

Hello,

I use ArchLinux, the official version of gcc for ArchLinux is 4.8.2. 
TeXworks include a pdf viewer and use a TeXworks version built with gcc 
4.8.2 the zooming function of the pdf viewer is slow and uses a lot of 
cpu. I have built gcc 4.7.3 in ArchLinux (modifying the CC, CXX and LINK 
variables in the makefile) and used that gcc version to compile 
TeXworks, with that build the zoom function is smooth and the cpu usage 
is lower. I don't know if that is a bug, a compiler switch missing o 
something else.
I don't have to knowledge to investigate this myself, but I could give 
more info if somebody needs it and tell me how to obtain it.
Thanks.
