Unwanted Zoom Flicker when switching between image tabs

[Madpeaz]

My issue is when tabbing between two images or more, of which are all at 100%, each image will in turn ZOOM to fill the screen/workspace before it goes back to 100%. I find this quite annoying, especially if I'm trying to compare something like a 'Before & After'.

I have set in Preferences, Limit initial Zoom to 100%, but that does really help my case, in fact it does exactly the same as tabbing between two images.

The Zoom issues I believe have been raised in the past, in regard to cropping, but it would be a whole lot nicer experience if the epileptic flicker would disappear! Or at least give an option somewhere to turn it off. The issue was in 1.10, though it was a shade slower and didn't look like a really horrible screen glitch.

I personally, do see this as 'bug', as I cannot find a useful purpose for an image to Zoom up to nearly 200% and back down 100%  in 1/500 sec.
In the attached example video, there is one point it didn't Zoom up! - Now that is a friendly bug we need a few more of them.

Thanks for all the effort that goes into this software, I now use it 90%.

Check under Preferences>Performance tab...

Try changing Retena Rendering from Auto to High. This can cause artifacting. Especially when scaling elements or panning. If that doesn't work, try turning off OpenCL.

I have the same issue. This issue occurred in the V1 apps, too. I find it frustrating, as well — it makes comparing two documents difficult.

I have Hardware Acceleration (OpenCL) disabled. Changing Retina Rendering from Automatic to High quality didn’t have any effect for me.

Could be Nvidia G-Sync related?

I have an old PC with an AMD Radeon R9 graphics card. I don’t know if the age/performance of my graphics card could be the source of the issue.

Thank you for the suggestions, I have tried those suggested, alas none made any difference.

But in my opinion and my experience, this is a bit of a bug. Maybe just a Windows thing, I don't know?
My computer is not slow by any means with an i7 CPU & Quadro grapics card, tabbing between two images shouldn't be too taxing, even on a low spec machine.

As mentioned, it needlessly zooms to fit screen and back down to 100%. If that glitched could be removed, that would be great.

I believe I've found the issue. 

Preferences > General > Untick 'Limit intial zoom to a maximum 100%' then restart (I had to restart for it to work, despite not being prompted'

I noticed the zoom on the first post was 100% which lead to this discovery!

Thanks, Alas, I tried that too, done exactly the same as you did.
Some of the images I work with are of fairly low resolution, around 800px width, and so I want to see them at 100% actual size.
If the images were around 5000px width, that's fine fitting to screen when tabbing between them, you don't really notice the jump. But on smaller images, you do!

Well this is a workaround - not a fix. I still need to get this logged as it should be seemless.

@Madpeaz Thanks for bringing up this issue. I assumed the behavior was inherent to the apps, so never considered mentioning it as a bug. I’m happy to know the issue will be fixed!

Chris B thanks for your help, and for getting it logged. It will be a good one to resolve 👍
