I am experiencing a glitch when export photos from Affinity to a desktop folder. Please could you help me. See the attachment. Thank you.

Welcome to the Serif Affinity forums, @Barbora Pachmannova.

If you're referring to those fine white lines, try disabling Hardware Acceleration (OpenCL) in Photo. Edit > Preferences, then switch to the Performance section, and you'll find that option near the bottom of the list.

@walt.farrell thank you for the advice. Unfortunately, nothing has changed. Furthermore, it's even worse.

Hi @Barbora Pachmannova,

Welcome to the Affinity Forums & I'm sorry to see you're having trouble!

Usually disabling Hardware Acceleration would resolve this issue, so I'm going to need more information here.

Can you please navigate to Edit > Preferences > Performance and provide a screenshot of your settings?

What GPU is your system using, and what version of GPU driver is currently in use?

Many thanks in advance

please the attachment. 

Not sure about GPU. Where I can find that info? 

Many thanks.

Many thanks for the screenshots and information provided!

Please try downloading the latest driver from the following link -

https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html?wapkw=i5-1135G7

With this downloaded, follow Intels' instructions for performing a 'clean install' -

Once these are installed, restart your device then open AP and try exporting once again, does this resolve the error for you please?

Hi Dan C,

Many thanks, it's working (for now 😁). I really appreciate it.

Dan C,

I have another problem 😆with colour change. When opening in Affinity pic has changed colour. Please see attachments.

[Ron P.]

The color was not changed, it's just duller and flatter because no Exposure or Tone Curve was automatically applied. This is set in the Assistant Manager. In the Develop Persona, you have the ability to develop your RAW images without or with Affinity Photo's applying these. What you're seeing before is a JPEG embedded in the RAW file, and has various adjustments applied.

So if you choose to have your RAW file start with those adjustments, just click on the Assistant Manger and check boxes beside them. My personal choice is not to. I want to make all the decisions on how I want my images to look.

[Dan C]

Although the above changes may help alleviate this issue, there is a known bug with certain blue tones in RAW files being rendered with a purple cast and I believe this issue is also appearing here - this bug is logged with our developers, so I'll be sure to 'bump' the report now

Sorry if I revive an old thread.

I'm experiencing glitches (same as in the image posted here) when exporting images to JPGs on a laptop with a new Intel 13th gen processor.
I've already tried disabling OpenCL acceleration and updating graphic drivers to the latest release but I can't get rid of those glitches.

Anyone else experiencing the same issue on these new cpus?
Any suggestion how to fix it?
...should I switch to v2 Affinity programs?

[Dan C]

Sorry to hear you're having trouble @Peach1200!

I am surprised that disabling Hardware Acceleration has not resolved this issue for you, as this usually resolves the issue for other users. After disabling Hardware Acceleration, did you restart the Affinity app before exporting the image once again?

We are aware of issues in Affinity V1 when using Intel Xe/Iris Graphics, which your laptop may be using. These have been resolved within V2, so you may want to try a free trial of V2 to see if this issue is resolved for you, alongside trying the new and improved features -

I hope this helps

hi @Dan C
thank you for your prompt reply.
I had a look again at what was happening and noticed that my starting image already had glitches in it! I guess it's from an initial batch of images I resized without disabling hw acceleration.. my fault! 

I still have to make a few tests but I think you're right: disabling Hardware Acceleration should indeed solve this issue! 
thank you for your help
