Affinity glitching out

[Marvin lee]

Everything working fine then all of the sudden this happens. One of the layers suddenly blacking out when I try to zoom in/out, part of the background image now has a rectangle with different colour. Even when I export, the glitch appears.

Hi Marvin lee,

Welcome to the forums

I'm sorry to hear this, it certainly isn't something I've seen before. Could you please save your .afphoto file and upload it to the following link? This will allow me to investigate your issue!

Thanks for your reply. I have uploaded my file. I am really loving affinity and have been using it everyday for the past month and have had no problems besides the odd crash/lag here and there but those problems go away when I close and reopen the app. I’m hoping this is something easy to solve (maybe a photo layer that’s corrupt or conflicting), and I hope this will help you guys as you continue to develop the app. 

I am on deadline with this project tho, so I’ll try to rebuild it again but if the same thing happens again, I will have to try a different app. 

Thanks again and have a great day.

Update: I’ve rebuilt the project and there was no problem. Still would like to know what could’ve caused this to happen.

Thanks for your file, I can see the Body layer is causing the issue here, rasterising the layer produces the same blackened layer, as does cutting and pasting the layer back in - this is something that myself nor our QA team have seen before!

I'm not currently 100% certain what may have caused this, I've checked the file and layer settings and there's nothing inherently 'wrong' with anything here.
It looks as though the Mipmap has not updated correctly, causing the pixel layer to be corrupt. Below 50% zoom the layer displays as you'd expect, as soon as you pass 50% the layer is darkened so I'm going to log this file with our developers to be investigated. 

Unfortunately without the documents history or a workflow, we can't be certain what caused this pixel layer to be corrupted, so I'm hoping our developers may be able to provide more insight. Did you apply any filters or effects to this layer, or manipulate it in a way that may have changed the pixel contents?

I'm glad to hear you are not seeing the same issue after rebuilding the document, my apologies that you had to do this here.

Everything was going fine and I think it started happening after I added the title text. And right before that, I added a pixel layer, with a gradient (turquoise/purple) and had it on multiply.

Thanks, I'll be sure to update you with any information our developers can provide

Awesome! Thanks and have a great day
