Delay on display of Layer Thumbnails

Recommended Posts

I always seem to come across this issue, there is a substantial delay to display the layer thumbnails. Is there something I can do or adjust on my Mac to remedy this? Just wondering if really high performing computers experience this delay.

This is something I experience quite often. It seems to happen when there is 'heavy' graphic content in the file, as in lots of layers with complex layers or lots of effects added to layers. I'm running with 16Gb of RAM but still see the same thing from time to time.

I've also experienced the situation where complete layers vanish from the layers panel leaving a blank space between layers. These can sometimes be recovered by colapsing the group and opening it again, so it very much sounds like a screen re-draw issue possibly combined with a memory issue.

Maybe someone from the support team can provide more detail as to why this may be happening. It doesn't impact the file itself but obviously just leaves you with no instant thumbnails updates.

User Jaffa reported this last summer:

I commented there that I too have this happen at times in v1.7. Though it never happened to me in v1.6.
I still have it at times in v1.8 But as yet I have found no consistent set of circumstances or steps that always make it happen. I know, not what any developer wants to hear!

Noticed this thread had come up.  I really don't seem to have the problem now.  Not too long ago, I upgraded my tower to an Intel i7 9th Generation chip (8 core and 8 threads), with 16 Gig of DDR4 RAM and kept my older graphics card.  The i7 chip has a lot of graphics capability, even on its own.  So, my guess is that it needs a lot of 'oomph' to get and keep the thumbnails in the Layers Panel.   Before that my older AMD 6 core chip, even though very fit for all other software uses, did struggle to keep up with my demands on it when using Affinity Photo - I registered 100% usage at times.  I use layers in virtually everything I do, etc.
