Adafruit Permaproto causes lag


#1

Steps I took that resulted in the problem:

Import Adafruit Fritzing Library


Place the permaproto half size (any other should do as well) board and add a few components
editing will become very slow and laggy

What I expected should have happened instead:

should be smooth and responsive

My version of Fritzing and my operating system:

0.9.3, Windows 10

Please also attach any files that help explaining this problem


#2

Happened to me when there are too many detailed parts at the same time and you zoom out. Seems to be a problem related to program perfomance which can’t be solved right now since there isn’t maintenance from devs.


#3

Try turning off the grid feature. If it is set to a low value it can cause massive lag. If turning it off helps but you want to use it then set it to as large of a value as you can use.


#4

I can confirm that there is a significant reduction in program performance when any size Adafruit Perma-Proto PCB is used added to the BB window. I Also reproduced this lag with a similar setup as you are working with (Win-10 & Fritz-9.2b).

Would you please post an example sketch which shows the slow response time? I tried with an older (2017 vintage) adafruit part and don’t see an unacceptable reduction in response on 9.3.b on Win7 pro, but there may be a later version of the part that reacts worse (or I may have used the wrong part :slight_smile: ).

I noticed the same thing today on Ubuntu. It wasn’t a problem when I tried them 1-2 year ago. As soon as I started trying to place any parts on the board, each hole would flicker blue really fast as the parts passed over it. I’ll try my older Adafruit library to compare.


#7

Interesting, because I’m not seeing this even with the latest adafruit version on 9.3b and win7 (or I’m using the wrong parts). Check your view->set grid size is set to the default .1 in (finer grids are known to cause this problem) if you haven’t already. If I could get it to reproduce I’d look at the coding of the part as being the likely performance hit (but as noted I can’t reproduce this so far).
