Won't load

I have been using Debian 2.8 version successfully.  Being a new setup I have been using the wizard to make changes to the same program often. Eventually the screen showing the tool path showed only horizontal lines.  Then the program would start to load and hang up the whole computer.  Couldn't use the mouse for anything.  Seemed like it was in a loop.  Maybe I should do a reinstall?  Older computer but was working fine.  Not sure what to do or look for short of a reinstall.  What is the most stable version?

Thanks in advance for any help.

 

Solved this problem by cleaning out the "tray". had about 12 wifi connections showing up every time I booted the computer. One more every time. I think this just took up too much processor time so graphics would work correctly. Emptied the tray and everything went back to normal. Even makes ethernet connection immediately when booting up.

Have a look at point #1 here: forum.linuxcnc.org/38-general-linuxcnc-q...little-issues#226480

This will permanently solve the network manager icon (tray) problem.
