AD b2075 -macOS - redraw errors in Outline view

[ronnyb]

Two issues:

1) As you can see while doing a step and repeat of the square, the horizontals are not redrawn in Outline view.

2) Also noticed that diagonal lines are breaking up while using the Hairline View mode, under Advanced View Mode...

Hi @ronnyb,

Thanks for your report!

I'm not seeing this issue here currently, are you able to provide a copy of your Affinity Document which shows this bug?

Just to confirm, are you using CMD + Y to switch to the 'Last Used' Wireframe View mode in your recording?

Many thanks in advance

Hi @Dan C, so I went to grab the file that was exhibiting the issue, but it's rendering properly now... 

Yes, I WAS using Cmd Y to switch view modes during the screen recording; I was in Hairline view before switching back and forth between Vector view. Here's the UI element I use on the Toolbar:

 

Here are my Performance settings:

I'll keep my eyes open for it to see if it resurfaces....

That's certainly interesting behaviour, thanks for the further information provided also!

I've double checked this on my Intel iMac running Monterey, and an M1 MBP running Sonoma and I'm not seeing the same issue, so its possible this was a temporary rendering glitch which has resolved itself.

Please do let me know if this returns, or if you find a consistent way of triggering the issue

Hey @Dan C this bug is still present in the recent 2.3 GM/public release. Attached is a file showing this bug, hopefully you guys can see it on your end. Also attached another video for your reference.

Thanks for your file and further screen recording provided - I've tested with this document on an M1 Sonoma MBP, and I'm still unable to replicate this issue.

As this appears to be rendering adjacent, it may be relate to the monitor/colour profile that is in use currently. Can you please confirm your settings under Apple > System Settings > Display for me?

Hey @Dan C sorry I missed your reply way back, @EmT was kind enough to remind me the issue was still open. Attached find the Settings for the affected external display u requested. FWIW, I tried to trigger the redraw bug what was unable, I'll report back if I find new info...

Not sure if this is related, but it seems like the spiral is misrendering in Vector view mode too, as you can see the bottom sections pointed out have an interference pattern where every fourth line segment is rendered darker, as a 2 pixel line, instead of as a brighter, one pixel line like all the other segments, as the close-up shows. Oddly, it only misrenders on the horizontal segments of the spirals, not any of the angled sections...

[Dan C]

No problem at all, many thanks for providing these for me!

If you are able to trigger this issue again, please try changing the Colour Profile assigned to your monitor in macOS, as I believe this may be the cause of this - 

Equally, I've tried replicating the settings I can see in the screenshot for your spiral and I'm not seeing this issue currently. Are you able to attach a sample document for me?

Does this Spiral Tool / Hairline View issue occur only when viewing the app on your external monitor? I have a feeling that the below issue you've reported regarding Artboard names may be related to this, and could explain why I am not seeing the issue on my single monitor iMac -

Thanks in advance!

Attached. Also sent screen recordings of spirals on built-in retina display on my MBP with both OpenGL and Metal...

I was thinking that the horizontal rendering issue on the spirals may be a natural byproduct of the rendering engine approximating with brightness what it cannot do mathematically / via the pixel grid, for accurate spacing of the arms.... and of course it would be most pronounced on straight horizontal or vertical lines that don't fall on a whole pixel location.... but i'm not a programmer so.......

Yes when I drag the app window to the built-in display it renders properly, with the correct font and smooth anti-aliasing, but when it's on the external display, it renders the title in a weird font (as if it's missing the font file) or the anti-aliasing is all messed up....

[Dan C]

Apologies for the delay once again & thanks for your file provided!

I believe there are 2 separate issues occurring here, firstly using the document you've uploaded, I can replicate rendering issues on both macOS and Windows, which I believe are specific to the Spiral Tool. The following is what I can see on Windows:

These sections of the Spiral appear to render differently based on zoom level and don't follow the rendering of the other sections of the spiral - therefore I'm getting this logged as a new bug with our Designer team now.

Secondly, the issue you're seeing with these Spiral section lines not being rendered correctly in Hairline View mode is indeed related to your Artboard Title report and is caused when using Affinity across 2 different sized/resolution monitors - which is why I was unable to replicate this on my setup originally.

I've now updated the development log for your Artboard Titles with a copy of this document, showing the issue you've previously provided a recording of:

I hope this helps

Thanks @Dan C, glad it helped. Two comments on the statements quoted above:

1. Perhaps the rendering issue on the horizontal and vertical lines is bc it's antialiasing to "split the difference", ie, make te lines visually fall where they should, even though it doesn't fall on the pixel grid...? 🤷‍♂️

2. Check out the Artboard Title report, I just updated it today with a spreadsheet of screengrabs across all possible launch types on dual monitor/diff resolution displays: 

 

[Dan C]

No problem at all!

I do believe that the general rendering issue is due to antialiasing, though our developers should be able to confirm this and hopefully improve this in the future.

Thanks for letting me know regarding the Artboard report, I'll be sure to inform Sean of this reply also
