Good point, I had been looking for such a setting but did not find it. To answer your question: not as far as I know. But I know now what to do about it. Thanks.

In Affinity Photo Beta 1.10.0.244 sometimes the Levels control shows no histogram. This behaviour is erratic and I have found no reliable way of reproducing it. The control itself may be responsive. After several minutes and possibly related to some action from my part such as saving the file or bringing up the "About" dialog, the histogram may suddenly appear. I have not observed it on every occasion, but then I might not have waited long enough. PS I have noted the same behaviour in 1.9.3.

Title says it all. The copy is smaller than the original. Checked with 1.9.3, there the size stays the same. I can reproduce the behaviour. See attached. screen shot.

Thank you for this. This is what I am doing right at this moment. It seems to work much better so far. Actually, I am just submitting my first (unrelated) bug report... Thanks again.

Thank you for this reply. Unfortunately, I purchased my version from the Mac App Store. I will reach out to Serif to see if they can help me.

As I mentioned in a reply to another thread, Affinity Photo AP 1.9.3 is unusable for now on my iMac due to frequent freezes. I have a project that needs finishing. I would like to temporarily go back to 1.8 or even 1.7 (which I know worked fine for me). Is there a way to download an old version to help me out? Thanks in advance, Jeroen,

Same here. I do not think you are expecting too much. I have been a very satisfied Photo user for years. The controls used to work virtually instantaneously. But not anymore. Coming back after a pause, with 1.9.3 I constantly have freezes. So bad that I first thought that I did something wrong, since (for example) twiddling with the Levels control did absolutely nothing. Only after many seconds it appeared to work after all. I am not doing anything out of the ordinary, compared to what I did in the past. A few layers with one or two live filters, that's all. One file at a time. Also, I noticed that with the Levels control sometimes the histogram does not show, at other times it stays at the master display when I am on red. Once, after saving the file, the histogram suddenly appeared. Could be due to the same freezing behavior, cannot be sure. I also found that a Levels control that (sort of) works at the global level becomes unresponsive if I move it to be subordinate to a layer (with mask). That is, sometimes this happens. Could again be a temporary (but long) freeze. I do not think that there is anything wrong with my system, or with the files I am editing (300 MB or so tiff files). System is an 2019 iMac, 3.7 GHz 6-Core Intel Core i5 processor, 40 GB 2667 MHz DDR4 memory, Radeon Pro 580X 8 GB video card. The system is lightly loaded. I am running the latest version of OSX (Big Sur 11.4). I hope that Serif is paying attention. I have always found Affinity Photo an excellent alternative to Photoshop and I have been an active ambassador for the program, but based on this version I cannot recommend it to anyone. Please have this fixed ASAP. I have a project that needs finishing. (If there are any tests I can do that could help find the cause, I will be happy to help. I know about computers.)

Hi Justin, Interesting.I can see that NaN values might certainly cause erratic behaviour. The question of course is where they come from. You are correct in that I developed from a raw file, and I did it in AP. I do not keep records of develop adjustments. Normally I tend to keep development settings simple and leave most of the work to the Photo persona, but I do not remember exactly what I did here. I can provide the raw file though, if that might be of use. It is a Canon .CR2 file. Let me know if you would like me to. Best regards, Jeroen.

I could not replicate it, but I recall having noticed similar behaviour at other times. If and when it reoccurs I will report again, with as much information as I can.

See attached image. The HSL adjustments and WB adjustment suddenly stopped working. The Levels adjustment still worked.I made a recording of the "HSL lucht" adjustment not reacting, also attached. Maybe it is relevant that I have layer masks on the HSL and WB adjustments, and not on the levels adjustment. After saving and reloading the project, the problem had gone away. I therefore suppose the project file would be of little value in diagnosing the issue, but I kept it safe and can upload it if requested. For the record, I had Metal compute activated and the project is in 32 bit HDR. Schermopname 2019-07-12 om 11.08.02.mov

I uploaded "About this Mac' to the Dropbox link you provided. Please let me know if I can be of further help.

Uploaded. Please let me know if I can be of further help.

Thanks for the encouragement. I now have a workaround. Yet, I may misunderstand you here... but it seems to me there is definitely something wrong at the moment. I have a 2019 Mac with all software up to date. You are certainly not suggesting that Metal support is fine as it is, and thus needs no fixing? Then, why is it not working as expected?

Disabling Metal compute does indeed fix the issue. I have uploaded the file to the link you sent me.
