Lasso Tool (Polygon) Issues

[DarkScythe13]

Hi, I’m not sure if this has been reported previously (I can see other threads relating to issues with the lasso tool but they seem more related to crashing).

 

Ive noticed two particular issues for a while now with V2 that werent present previously in V1:

• At times when using the polygon lasso tool, i have experienced an issue where ive carefully selected the outline of an object, sometimes a whole stack of unrelated pixels will also become selected in a weird rectangular like shape. I wish i could demonstrate but its hard to replicate, only happening occasionally.
• Have experienced an additional issue as of today where selecting with the same tool (lasso polygon setting) does ‘select sn object’ but the marching ants arent updated  right away, requiring me to first zoom in and out to forcibly update the display.

Has anyone else experienced similar?

Until you mentioned it I hadn't even realised there was a polygon lasso tool, since I always use the pen tool in smart mode instead to create a rough shape that I want to be a selection, then I use the node tools to tidy the shape up, finally I return to the pen tool and then tap 'To selection' on the tool bar. I find this workflow much more accurate especially for objects with straight edges and curves.

Probably a nice trick to try. The main reasons I use the polygon lasso tool are because I use add and subtract functions to refine larger ‘selection brush’ selections, and because the polygonal part has always been quite flexible in allowing you to both manually drag complex areas, and then either pause if you need to readjust your hand and/or select large straight areas the intended way. That said i don’t know if my own hybrid use of it is part of the problem thats occuring (but again, never had it happen previously on V1 and has always worked great for my purposes)

Hi @DarkScythe13,

Are you able to record a full screen recording of this occurring with the layers panel visible?

@LeeThorpe Sorry for the delay. Is this sufficient?

I’ve been having a similar problem with the tool, it happens at complete random on iPad and it makes using the freehand selection tool a game of chance (edit: it’s also happening on Affinity Designer V2 as well)

That took some repeating but I eventually spotted that you have the freehand tool set to polygon but you drag the pencil as if you were using it in freehand mode.

In polygon mode you are supposed to tap tap tap around your selection which must be confusing the tool somewhat as it expects 3 or more taps/nodes to complete a polygon.. Simply leave the context toolbar setting as freehand not polygon for the way you are using it by drawing.

I tended to do so in V1 as I found that the tapping afforded by the Polygon Lasso was pretty nifty when used in combination with the ability to drag, effectively breaking down some more complex selections. It meant being able to undo them or having certain checkpoints so to speak. Id never really had that issue in at all in V1.

ill give the freehand mode specifically a try from now on out of curiousity (I know there are simple alternatives like using the add selection button which can achieve ultimately the same outcome. Someone above did comment they they use free selection and it still occurs to them so I’ll report back if it happens to me.

I have found a few wierd issues with V2 since using it (every so often i have to pinch zoom in or out because a recently drawn raster brush layer disappears until forcing a screen update for example) and as well as a previous issue id raised (magnifying occurring when altering perspective, causing the app to experience frequent pauses), so I feel regardless the issue occuring on the Polygonal Tool is still worth raising (especially if it is in fact to do with the tool itself) so it can oerhaps be picked up on and potentially be fixed.

I can definitely say the issue has also happened in freehand mode unfortunately, agreed that the issue still should be addressed

Just an update, Ive found this also occuring when using the smart selection brush also (upon lifting the apple pencil and thus ceasing further selection). As shown between the two images, it is fine until the moment of having released. It does indeed also occur with the non polygonal lasso. Adjusting the DPI from 72 to 150 seemed to stop the issue from happening.
