@hotpurple The only workarounds I've found are to turn off metal and to turn try different values in frequency separation sliders until maybe one works. I haven't found a pattern yet. I've been trying to get Affinity to fix this bug for 2+ months now without success.

@Gabe how long will it take to get a response from the developers? I haven’t been able to use frequency separation reliably for the last couple months.

@Gabe I've uploaded the crash report as requested.

@Gabe do you have an email address I can send the crash report to? I don't want to post it publicly in case there is sensitive data in it.

@Gabe I’ve also sent the image file, steps to reproduce, hardware and OSX info. I’m software engineer so if there is anything I can do to help you let me know. I’m in California USA in case you have anyone out here who wants to see it happen live and debug it. I’m also willing to run a debug build if you have one that collects more info on the crash. Really want to get this fixed soon.

@Gabe I sent you a screen recording on December 23. Please see above in this same thread.

@MEB were you able to reproduce this yet? I can use frequency separation with metal disabled, but it's very slow and painful. Really hoping we can get a fix soon. Thank you.

I've uploaded a RAF and my system specs. If you need any additional data from my system please let me know. Happy to test a build if you are able to fix the bug.

I have confirmed it crashes on a Fuji RAF file. Previously I said it crashed on a TIFF generated from Capture One. It appears this bug has nothing to do with Capture One. File attached. It crashed for me when I set frequency separation radius to 39.8px. I have also confirmed that it appears to only crash when Metal is enabled. I tried multiple times. 0/2 crashes with Metal disabled. 2/2 crashes with Metal enabled. Hardware is attached. DSCF9048.RAF

Not sure. Do you want an image that demonstrates the crash? Do you want a crash report? I would like to get this bug fixed as frequency separation is extremely important to anyone doing retouching with Capture One. Any ETA on a fix?

My specs: I can reliably reproduce this issue. My workflow is to export TIFFs from capture one and edit them in Affinity Photo. Because this crashes so much I basically can't use Frequency separation at all.

I am having the exact same issue. OS X 10.15.2. Affinity Photo 1.7.3. Every time I try to use Frequency Separation it crashes. Makes sure you set the Radius slider to the middle. If you leave the Radius slider all the way to the left then it won't crash. I have also attached a screen recording. The file I'm editing is a 26 megapixel tiff exported from Capture One. Originally it was a Fuji XT3 RAF (raw) file. Screen_Recording_2019-12-23_at_4_50.46_PM.mov
