Affinity Photo Layers become invisible after zooming

Recommended Posts

I have a project that involves compiling various "pages" of a map into one big page. Each page is layer.

Once I had more than about 6 pages (layers) I found that when zooming, the layers all become invisible. If I quit affinity and re-open then usually they are then visible again. The file size is quite large but not huge, dimensions are 4000 x 8000px and the .afphoto file is 62MB, however I believe my iMac Pro should be able to handle that easily

  • 3.0GHz 10-core Intel Xeon W processor, Turbo Boost up to 4.5GHz
  • 64GB 2666MHz DDR4 ECC memory
  • 1TB SSD
  • Radeon Pro Vega 64 with 16GB of HBM2 memory

I am attaching a screenshot

I have uploaded it.

 

Just did a bit of editing work and the issue did not happen, but it seems to happen whenever (or soon after) a new layer is added

Hi Mr Lucky,

Thanks for the file. I'm struggling to replicate the zoom issue you have shown in the video. This is probably a redraw issue that may be related your specific graphic card/drivers.

I'm passing the file to a colleague to see if we can reproduce this on other systems.

Could it be related to specifically happening afrer pasting in a layer? Because that's what seems to make it happen here.

 

Also seems slightly related to a previous issue I had after pasting in a lyer (but not on the same computer)

Looks like I can now reproduce this almost every time.

  • Zoom out to about 10%
  • Paste in the next layer
  • Zoom in to 125%

Hey Mr Lucky,


MEB asked me to see if I can reproduce this but I've been unsuccessful. I wonder if perhaps it's the GPU you are using. I'll need to see if someone in the building has a Vega card installed. I'll get back to you shortly.

The Vega was specifically recommnded at the Applestore (ie by a tech specialist at the actual physical shop) , I made them aware i was using Affinity so I'd I'd be a bit miffed it is is not compatible, especually as Affinity is an Appstore product.

One more thing regarding this: it seems I can work happily with no issues if I leave the zoom set at around 80%. The issue only seem to happen when zooming in.

However if I save with the zoom set at 80%, when I re-open it always seems to be back to 21%. If it could save the zoom level I'm working with, it would at least allow me to work without so much of this annoying issue which seems to only happen with combination of pasting a layer and then zooming, or zooming then pasting a layer.

Whilst we wait for dev to get back to me about testing on a Vega card, can you go to Preferences > Performance and change the Display to Software and see if you can reproduce the zoom issue. 

Out of curiosity, what is it currently on?

It was on OpenGL

Use ponly integrated GPU is unticked

 

I will change to software and try later this afternoon.

No still does it.

Having changed it to Software performance is bad - everything is very slow so I'll switch it back

That was just to check to see if the issue was with your Vega card. If it's still doing it whilst on Software, it is likely to be something else. Try OpenGL Basic and Metal too. 

The fact your machine is high-end and mine is pretty basic for today's standards is perplexing...

Also, how do you paste your layers in? Do you copy from a particular application and then just paste or do you have a different workflow?

If you save your document and load it back in, does it draw correctly at all zooms? 

Yes, my way to fix it is to save and reload. Then it's Ok until the next time I paste a new layer.

I paste from a different image within Affinity. This project at the moment is basoically making screenshots, then opening each one in Affinity and pasting into the "master" and lining them up to create a map from lts of small areas.

OK, after experiemnting, it seems to be fine if I use metal.

Can soemone please explain what this actually means though? I mean what are those settings?
