FYI...

Just in case there are others that use or have used DIA...

Several years ago I used the DIA Diagram Editor a lot for diagramming networks etc. It was a great simple to use tool!

To install on ubuntu: sudo apt install dia

A couple years went by where I'd not needed to use DIAt and during that time Ubuntu went through at least 1 LTS update.

In the past couple months I'd been working on a project that I needed to produce some diagrams for again and started to use DIA again.

But for some reason its performance when entering/editing Text was really terrible with sometimes long delay's between a "click" and an action.

I had been searching for any info on reports of this and any possible fixes.

Today I discovered the fix and it had to do with the massive number of Font's that are enabled in Ubuntu.

So following the Tip I read I installed the application font-manager.

$ sudo apt install font-manager -y

The fix... run font-manager and disable all fonts but the ones you actually use!

After that DIA's performance will be back to normal!
