Description fexpop 2008-05-26 13:30:34 UTC 
Version:           0.6.80 (using Devel)
Installed from:    Compiled sources
OS:                Linux

When you scroll through a dvi file with graphics included the scrolling will pause very frequently making it impossible to smoothly read through a document.

Kind regards,

Felix

It would be nice if you could include such a file.

SVN commit 966599 by pino:

Switch from the sync API to the async one.
Protected the potentially concurred methods using the user mutex.
Removed the manual 'ready' flag and the calculation of the bounding box, as both are done in the core.

This should avoid the block when rendering pages and extracting text from them, and reduce the "slow" feeling esp when invoking external Ghostscript.

Hi Felix,

would be nice if you could either:
a) attach a DVI document (and its external graphic files, if needed) showing the issue
b) try again with KDE 4.3.0

Thanks

Hi Pino,

I switched all my TeXing to use pdfTex, so I haven't seen any issues for 
a while. I have no objections against closing the bug.

Regards,

Felix

This appears to be a duplicate of bug 192284. They are the same with the exception that this bug explicitly mentions .dvi's with graphics whereas the other refers to all .dvi's.

Closing the bug, please reopen if you still find this to be a problem
