@carl 123: The curves layers are the root cause for the slow down. Of course, disabling them makes Photo faster. But this is not the solution, it only describes the bug. slow_selection.afphoto

Hi carl123, the original file used in the video was quite large (>600MB), and failed to upload to this forum. To reduce file size, i copied only the relvenat layers into a new file, and verified that the issue occurs with the smaller file. Upload failed again, so i finally switched to the amazon drive link. I tried the same file with my iPad 2018, it is much faster vs. Windows, but still shows some slowness (below 1 second) I observerd similar issues more than once with older Affinity Photo releases, my high end PC is by factor 10-30 slower than the iPad in many situations, e.g. when switching to tone map persona. It is way faster in all other aplications, e.g. web browsing, video editing etc. Performance clearly depends on file size (megapixel count, color depth e.g. 8/16/32).

Are you using the latest release version? yes Can you reproduce it? yes Does it happen for a new document? If not do you have a document you can share that shows the problem? https://www.amazon.de/clouddrive/share/iQJ8gbNrwzgJCxGzsQaOolSRTuTpgQKiqroeS0Jr4pb If you cannot provide a sample document then please give an accurate description of the problem for example it should include most of the following: What is your operating system and version (Windows 10, OSX Mojave, iOS 12 etc)? Windows 10 1909 What happened for you (and what you expected to happen) there is a lag of 1-5 seconds between mouse mouse movement and visible effect i expect no noticable lag, or maximum 150ms Provide a recipe for creating the problem (step-by-step what you did). use sample image above select lowest pixel layer select "selction brush" select any area, e.g. one of the beach seats press left mouse button, move mouse to cover a small area, release mouse button wait for Photo to make selction visible. it takes much too long Screenshots (very handy) or a screen capture/video. https://forum.affinity.serif.com/applications/core/interface/file/attachment.php?id=136382 Any unusual hardware (like tablets or external monitors or drives that may affect things) or relevant other applications like font managers or display managers. no. plain vanilla PC Nvidia Gforce GTX 1080 OS Name Microsoft Windows 10 Home Version 10.0.18363 Build 18363 Other OS Description Not Available OS Manufacturer Microsoft Corporation System Name System Manufacturer MEDION System Model ERAZER X7731 D/C485 System Type x64-based PC System SKU ML-110000 10021768 Processor AMD Ryzen 7 1800X Eight-Core Processor, 3600 Mhz, 8 Core(s), 16 Logical Processor(s) BIOS Version/Date American Megatrends Inc.

Hi @Gabe, i hope only the image was missing.To reproduce, select the lowest pixel layer, use selection brush, and try to select any portion. Selection lags about 3-5 second behind the mous movement. record_000003.avi

Dear team, after upgrading to latest release, performance issues with selections start again. While using selection brush, flood select tool, or refine mask, Photo becomes totally sluggish and freezes many times. Issue most severe after adding filters / adjustments above the pixel layer. I'm talking about 2 curve layers, not 10 or 100 layers. Example file can be downloaded https://www.amazon.de/clouddrive/share/iQJ8gbNrwzgJCxGzsQaOolSRTuTpgQKiqroeS0Jr4pb For video, see post below. RGBA/32 Widnows 10 latest lots of free CPU, RAM, and GPU power

It is possible. Just change the “channels” from “master” to ”alpha” and the curve will affect the mask instead of image.

when using a mask, and reducing the opacity of the mask, this will always recude the opacity of the underlying layers, instead of increasing. This behaivior does not make any sense to me. Masks are used to filter out unwanted parts. When you reduce the mask's opacity, you want to (temporary) reveil the hidden parts again. You can disable a mask only completely, but in many cases you want to reduce only the power of the mask by e.g. 50%, meaning black pixels in the mask should act like 50% gray when the mask's opacity is set to 50%. In the moment, i found only a complex workaround: adding a curves adjustment to the mask, select the "alpha" channel, and lift the left node from 0 to e.g. 50%. This requires several mouse clicks, and works only if the mask is not nested, because Photo does not allow to add layers to masks when a mask are already nested. To summarize: If i set the opacity of a mask layer to 50%, this should show an effect equivalent to an alpha channel curve layer to the mask, where the lower left node is set to 100% minus opacity. The attached file shows the results of Affinity Photo when setting the opacity of the mask, or the underlying layer to 100% or 50%, and the simulated result i would expect. To be honest, the reults are really confusing to me. Same results with AP 1.7 and 1.8 beta. mask opacity bug 2020.afphoto

You can see the issue with this file. (de-)activate the curves adjustment to see the difefrence. Tested on iPad (2017) and iPad pro (2018) mask opacity bug.afphoto

When using masks with opacity, in combination with an adjustment layer (which supports alpha, e.g. curves) to the mask, the opacity does not affect the mask, but the layers below the mask. Trying the same on the PC version (1.7.3.487) gives correct results: adjustments affects the mask.

Afphoto file used do demonstrate issue It seems the opacity of the mask is wrongfully applied to the layers beneath when a filter is added to the mask mask opacity bug.afphoto

Hi there, observing strange behavior when combined masks, transparency for the mask, and additional live adjustments or filters to the masks. Every adjustments/ filters which support alpha is affected, e.g levels, curves, gaussian blur, minimum blur. 1. if you use a mask layer, you can use the opacity to reduce the masking effect, e.g. to see what will be masked out. opacity 100 shows only pixels with white mask, and no pixel with black mask. opacity 50 shows pixel with white mask, and 50% transparent pixel with black mask. 2. when you add an adjustment or filter to the mask, even with all parameters at zero, the result changes: now all pixel with white mask will be shown 50% transparent, and pixels with black mask will vanish. 3. Is this a bug or a feature? FullSizeRender.mov

@Daniel: Tank you for those suggestions. I’m already aware of several workarounds, please do not post more of them. These are non-precise and hamper the workflow . In my view this is a AP bug and should be fixed. Whenever I applied crop with e.g. 3:2, AP should respect this ratio and automatically calculate even pixel counts during export with locked ratio. Other applications behave like this, AP should do, too.

@Danielcz: This might work in theory. My expectation to AP is that the software does the math for me Really don’t want to do that manually

I can confirm this issue in 1.7.2.

The issue occurs when using crop (and not later when exporting): When selecting 3:2 crop an using the mouse to reach 4500 for x, AP shows 3001 for y, see screenshot attached. I tried to achieve 3000 for y, seems to be impossible. Either 2999 or 3001, but never 3000
