Ticket #4272 - Pick radius flickering

[MuffinChocolate]

Hello,

I installed Freecad using aptitude, I am running XUbuntu 19.10.

1) New file
2) New sketch
3) Create line
4) Then do what I do in the gif.

Gif see attachments.

PS: I did set the pick radius to 10px, but yes, this occurs with the default setting of 5px as well.

Thanks!

I have realized this for quite some time and it makes auto constraints rather difficult to use. Since Abdullah is currently not around I didn't investigate it any further. I have the feeling that it is not always the case.

Hello,

Thank you for circling in on this UR_.

@chrisb:
I did not find an open bug for this.
I must say, reporting bugs even for someone with software development experience who also reported bugs on other projects is quite cumbersome.
It was difficult to find an issue search mask that does not expect an id but works with keywords.
Then I felt I had to register there so I made an account.
Then a guide says to ask on the forums first.
Couldn't use the credentials here, had to register again.
Didn't find a subforum specifically dedicated to this, so instead I posted here.

It seems to be a rather obvious bug, and I am sure I made a lot of mistakes trying to find a way to report this, but I feel like there must be a huge resistance for others if I am the only one that ended up here.

It is perfectly correct to discuss errors here first. Even if you and I think something is a bug, others may not or have already a solution in the queue or may tell you that the bug cannot be fixed by a FreeCAD developer, because it comes from one of the third party libraries, or there is an easy workaround.

What we see in most cases is no bug at all, but rather user errors.

And finally, and this is very important, you make the error known to the community and others can help accordingly.

What else can I do at this point? Anything you want me to try or supply?

I you have ability to do so, you can investigate starting from this point.

Okay, I have managed to compile freecad and do a bit of very primitive debugging.

I followed that call, checked the blame history, other commits were in the range of 3-8 years, this one is fairly recent. With 0 knowledge of the code I am just taking the blame approach here, maybe this bit of work will help someone with more experience working on freecad pinpoint this faster.

EDIT:
Hmm, the issue exists in 0.17 as well.
https://github.com/FreeCAD/FreeCAD/releases/tag/0.17

EDIT2:
And in 0.16 as well.

There is no archive of older precompiled versions for linux (that I know of), I just have to assume at this point that this has been there since forever.
