Magic wand crashes regularly


Recommended Posts

The German Affinity Photo 1.9.4.1065 (and the last non-beta version 1.9.2.1035) for Windows very often crashes (50% of all cases) if I do the following (see attached video):

  1. Visit a web page containing an image and put a screenshot on the clipboard (0:00-0:04).
  2. Switch to Affinity Photo and create a new image from the clipboard (0:04-0:11).
  3. Crop the image and rasterise it (0:11-0:30). So far, so good.
  4. Now, in order to make the background transparent, use the magic wand, press the mouse button over a white area and move the mouse in order to adjust the tolerance. This works for a few tolerance settings, but at some point (0:44), the application stops responding and has to be killed manually.
  5. For some pictures, this happens during the first second of mouse moving. For others (like shown), it takes a lot of fiddling to get a crash. For only around 50% of all images, everything works properly.
  6. This problem does not happen when I manually set the tolerance to a certain value and then just click (not drag) inside an area. Only the dragging produces crashes.
  7. This problem does not happen if I load an image from disk. Only images copied from the clipboard produce regular crashes.

As far as I remember, this problem first appeared in version 1.9.2. In 1.9.0, everything was correct (I think).

Hey anweid,

Thanks for the fantastic bug report. I followed this a number of times but I'm afraid I cannot reproduce it. The fans on my machine go nuts and my CPU hits 100% but it doesn't crash.

Are you able to provide some basic PC specs so we can attempt to reproduce on a similarly specced machine?

Do you get a crash report?

Affinity Store version - Go to %AppData%\Affinity\Photo\1.0\CrashReports\reports

Microsoft Store version - Go to %AppData%\Affinity\Photo\1.0 (Store)\CrashReports\reports

Beta - Go to %AppData%\Affinity\Photo\1.0 (Beta)\CrashReports\reports

You can acccess the AppData folder by pressing the Windows key + R on your keyboard and then just type %AppData%

I have a similar problem. The selection still works for me. But if I then apply the blur filter, for example, the programme crashes in over 50% of the cases. 
The CrashReports folder is empty. But I saw in Taskmanager, that Affinity create a bugreport.

Best Regards,
Heiko M.

This is what Windows tells me about my two computers (one at home, one at work). The i5 with 8GB crashes often (50%?), the i7 with 16GB less often (10%?). The i5 mentions pen support: This is because I installed a graphics tablet a year ago, which is not connected to that machine since several months, so I only use the mouse exclusively.

I forgot to add: No crash reports are available.

Buuuuuut: At least I now found a picture that reliably crashes even after saving to disk and opening it again:

  • By coincidence, I created a screenshot while a second monitor (4k) was attached, which resulted in the attached (stupid) image.
  • Saving, reloading, not cropping, not rasterising, but directly dragging the magic wand across one of the white areas very quickly produces a crash (only tested on the i5 machine).

@anweid If you want to post samples that are crashing the application, then I would zip them, because the forum software changes them during upload (except formats which are not common web formats).

Edit: Maybe I am doing something wrong, but with all your images I am not able to crash the application.

Same here, no crash, but as mentionned above you should zip the file before attaching it to your post.

What we meant is to zip the JPG file (or Affinity file) that you use and get the crash so we can test it.

Affinity files are already zip archives, so further zipping shouldn’t be necessary. There is only an issue with image file formats which are commonly used on the Internet.

My apologies, Walt. It was my understanding from a discussion way back that (like the most recent document formats of the legacy ‘Plus’ applications) the Affinity format is a collection of XML and other files in zip format. I’ve just tried to unzip a *.afphoto file, and you probably won’t be hugely surprised to learn that my attempt failed.

Hello,


can we please focus on the real problem again?
There are several problems here:
1) When using the Gaussian Blur filter, it can happen that the selection turns white.
2) When using the Gaussian Blur filter, Affinity Photo may crash.
3) Despite the crash and the crash handler, no reports are saved in the corresponding folder.
4) When using other filters, Affinity Photo may crash.

This is very frustrating. My system is up to date, all updates are installed.

In the zip file is my photo file with the selection.

I can't replicate your exact issue, but here is what I found. This is with the Beta and release versions.

Using the normal Gaussian Blur filter from the top "Filters" menu works fine all the time. Reversing pixel selections (Ctrl - Shift - I) or from the top menu does work.

Using the "Live" version of the Gaussian Blur works only on the main selection, the motorcycle. The only way to reverse the pixel selection is to delete the Liver Filter, change the selection and then create another Live Filter. There is no way to cycle throught the two selection without deleting the filter, changing the selection and creating another Live Filter.

All this with or without OpenCL. Using the Liver version makes the fan louder, which I think is normal. 

But I never got a crash.

It will probably be something with the hardware / software driver combination. If Affinity Photo would at least create a crash report, I think that would be more helpful.
But there seems to be another bug.
If the "crashpad_handler" is active, but no report is filed, although the message "Program not responding" is displayed.

Hello @anweid

I look for similar problems in the forum and find this solution from @Komatös in the post "Affinity Photo 1.9.2 frequently crashing on Windows 10":

Try with deactivated hardware acceleration (OpenCL-acceleration) in APhoto. Preferences --> Performance.

At the moment, it looks like this has fixed the problem.

Good luck...

Thanks @Joachim_L and @HeikoM81:

  • Zipping common web formats to prevent the forum changing these files is a good idea, but was not necessary in this case: I got reliable crashes on all images downloaded from this forum thread – even the ones containing only device specifications or the very small crashpad handler screenshots.
  • The crashes appeared when hardware acceleration was switched on (see attached screenshot).
  • After switching the acceleration off, I could not recreate the crashes anymore. Wonderful!
  • After switching the acceleration on again, I could also not recreate the crashes anymore. Though that's nice, it's got me confused now. Let's hope that the crashes don't reappear in the future...

This confuses me too, because I have the same graphics card and no crashes. Current version for me is 27.20.100.9466.
