Moderate cpu usage while idle, file access problems

[Jason Monschke]

I'm using TexStudio 2.3 on Xubuntu 13.04. TexStudio was installed from the Ubuntu repository.

If I open a file in TexStudio and then leave the program idle for several minutes TexStudio uses approx. 9% cpu (from command top). That's not too big of an issue especially since this is a quad-core machine. If I close TexStudio I typically have to also kill the process otherwise it continues to eat up cpu cycles and hangs up the shutdown sequence.

What is more concerning is that I am having trouble accessing files while running other programs. If TexStudio is open file access time is extremely slow. If I kill TexStudio everything goes back to normal. It seems that the problem is related to the pdf viewer because this problem does not occur until after I compile and view a .tex file.

I cannot reprodue this behavior (neither the cpu usage nor file access time). But I'm using Debian wheezy.
You might want to try TeXstudio 2.6.2 which got a lot of improvements and a complete new tex build system.

I've also reported this to the TeXstudio developers:
http://sourceforge.net/p/texstudio/bugs/772/

The problem still exists for me with TeXstudio 2.6.2. In the sourceforge bug report I attached two .tex files that should reproduce the problem. The problem seems to be limited to tex files that make use of pgfplots.

Thanks,
Jason

This problem is fixed by ensuring that the folder ~/.config/texstudio is owned and has read/write permissions by the local user.
