Title:
gschem file preview function renders files twice
Status in GPL Electronic Design Automation tools:
Confirmed
Bug description:
Just a minor observation here...nothing big.
After opening the "open file" dialog and clicking on a schematic file,
the preview window to the right renders everything twice. This is
quite noticeable on some of my monster schematics...you have to wait
for it to flash the rendered image two times before you can click on
another file.
Maybe the preview code is getting a duplicate signal from the file
window? Or maybe this is actually a GTK+ bug in the file chooser
widget...I'm not sure.
Cheers--
Julian
