[AP] Bug in 2.0.4: Artifacts when using "Merge visible"

[Imaginary]

When merging the visible layers Affinity Photo produces random rectangle artifacts (see image below bottom right), it takes a few repetitions until it works as expected.

Could you attach your afphoto file or upload it to our Dropbox here and I'll take a look at what could cause this to happen.

As a quick test, can you disable openCL in Affinity by clicking Edit>Preferences>Performance and unticking openCL at the bottom of this window and close Preferences, you'll be asked to restart Affinity and once restarted, try merging visible and see if the merge works first time.

Disabling OpenCl seems to work, but this also slows down Photo e.g. when zooming into large projects. Hardware acceleration makes zooming much faster but shows temporary artifacts similar to those when merging the visible layers. I have uploaded the file from my initial post to the dropbox.
