Screenshots are corrupted/shifted when pasting from paint.net into Firefox

[Thimble7804]

First up, apologies if this isn't a paint.net issue. I'm not sure where the issue is exactly, but I suspect its something to do with different standards of storing images in clipboards.

 

If you see the images (a screenshot from confluence), this is a screenshot of an Excel grid, taken using win 11 snap tool (shift+win+s). I paste this into paint.net (5.0.12) Then select all and copy/paste into Confluence using Firefox. The edges of the images are either shifted, or a line is added.

If I use paint instead of paint.net, it is ok.

If i use edge instead of Firefox, it is ok.

Saving the file as png (in paint.net) and importing it and its ok.

Pasting from paint.net into powerpoint and its ok.

 

Any ideas what is causing this or how to fix it? I'm going to ask atlassin (confluence) and firefox help as well.

 

 

Setup:

- Win 11 22H2

- paint.net 5.0.12

- (browsers listed in the images)

 

Workflow:

- find something to screenshot

- ctrl+win+s

- select the area

- ctrl+alt+v into paint.net

- either do some editing or not, doesn't seem to make a difference

- (still in paint.net) ctrl-A, ctrl-C

- click in the confluence cloud editor tab in browser

- ctrl-V

- image instantly pasted with corrupted edges

 

 

 

Thanks for reading!

Welcome to the forum @Thimble7804

 

The line that you are seeing on the pasted image is due to the behaviour described in this thread:

A bug in Firefox and/or Confluence

[Thimble7804]

That was a great answer. Doesn't fix my issue at the moment, but at least we know why.

 

I'll copy/paste some of that thread into my help tickets on Firefox/Confluence.

 

I wonder if its worth while adding a preference setting to restrict what paint.net adds to the clipboard? (given the issues with DIB and DIBV5).

@Thimble7804 When you've raised your ticket could you post the link for info in this thread please?

I'm interested in any Firefox discussions about this as I encounter the problem when pasting images to postimages.org for this forum. Yes, I know I could save to an intermediate file and upload that but it takes longer to do that.

By the way, I don't think there is any value in raising a ticket with Confluence since you are simply pasting to their web service via Firefox, which is where the problem lies.

Paint.NET puts a PNG in the first priority position on the clipboard. I'm surprised Firefox doesn't just use that instead of the DIB/DIBV5.

These are my support links:

My current workaround is to set the zoom to 100% and use windows snip tool to select the image out of the paint.net work area. Its marginally faster than saving the images (I'm mainly using it for quick annotations of things, so I don't tend to keep the images anyway).

I doubt you'll get much traction from those support tickets.

 

There's a Mozilla bug filed. Just give them time to address it.
