Affinity Photo Error

[GMPhotography]

Hi there,

So this error happened to me several times back in Beta 1.7 but since the release it hasn't done it till now so I figured it was solved. However, my copy is now doing the same thing it was before. When working on a bit larger files (this shot is 600x8500ish px, when I added things like levels and curves and then try and mask those with the erase brush form certain areas, it stops working and gives me a weird readout when resizing the brush.
I've attached a video of the problem via dropbox.
Thanks!

Greg

If you haven't can you try the latest beta to see if the issue is resolved. Have you also tried turning off Hardware Acceleration and changing the Display option in Preferences > Performance to see if this has any effect.

Hey,
Sorry I don't ever get notifications about responses here and I have a hard time remembering to log in to check.
 It still does it even in the current version (and Beta) except I discovered that it only happens when I've done a large focus merge, a larger stack, or a panorama (of any size). To stop it from happening, I adjust what I need to, export it as a tiff and reopen the exported file, and then I can continue working normally with nothing ill occurring. 
I have to do the export as soon as is possible, if I work to the point where AP does this to me, I can no longer export the file and have to start from scratch; it only exports a black image when the bug takes hold.
I will try turning off hardware acceleration, it's about the only thing I can try.
