It does. It won't save the image. Sometimes I have to use Task manager to shut it down after it does this. Log.txt is full of error messages. (I'm using the beta) Don't have the problem with OpenCl acceleration turned off. Doesn't happen all the time.

I have a medium One by Wacom. Its their most basic and cheapest model and is just a drawing tablet. No bluetooth. No shortcut buttons. I previously had a small Intuous that was getting a bit old and battered (I now have it in my travel bag with my laptop). I didn't use many shortcut buttons and the pen buttons give me two which is enough. I'm not a very sophisticated user. Its great for masking and brushes.

Some of these issues have been fixed in the beta. Also make sure your graphics drivers are up to date.

Maybe try it with OpenCL acceleration off to make sure its an OpenCL problem. There's this in  the FAQ's
 
 

Hi both,
I will get this logged as those artefacts you see in the Beta should not be there. But the dark spots you see in the release are excepted. 
Just a quick hint @RichardMH. I believe you're using OBS to capture your screen. Set the capture source to Display instead of app so we can see your pop-ups. Also, why are you working in 32bit? You have some negative values in those dark areas, when you apply that vidid light blend mode, you push them into very high values(mathematically correct) but will not look as expected on screen. 

If you can, when you start it up go into Edit->Preferences->Performance and uncheck Enable OpenCL acceleration.

Normally clicking on a selection which was saved as a spare channel shows a grayscale representation of the selection. This functionality does not work anymore in the latest beta.

They probably want this file

There's also a new NVIDIA studio driver 462.31 (Windows 10) that so far has improved stability with OpenCL acceleration on.

Added 'Limit Initial Zoom to 100%' preferences option (defaulted to off)  Fixed crash on document load when the OpenCLOn12 compatibility pack has been installed Added hardware acceleration to Gradient Map adjustment Fixed renaming a LUT preset to also change the name of the underlying ColourCubeRGB (so it manifests as expected in the LUT adjustment dialog) Fixed F-number always showing in the UI as "f/0" for Leica M-series cameras (and likely others)  Render EXIF exposure time as decimal (rather than fractional) if above one Implemented GPOS Cursive rule (used by "Charis SIL" font) Fixed PDF Export group opacity potentially being applied twice Previous release notes

I want to do something like I can do In ON1. There I click Browse, the image is saved and I'm back in my folder.

You gonna need to untick "Matte Edges" on your second refine. That should sort out your feathering issue. 

have you turned off OpenCL acceleration? Edit->Preferences->Performance (on windows)

Similar experiance as OP. Not usable. Nvidia 2070super...
Every time I use merge visible, I get square artifacts. 
When exporting as jpg as well.
Previous 1.9 versions were ok.
On the other hand speed is up 50%

You don't say what you are running it on. A lot of  the problems are due to OpenCL acceleration. Try going into preferences and Performance and turning that off.

@RichardMH | @iHarri | @TEcHNOpls, I'm going to delete this thread, because 1005 build has some significant changes to hardware performance.

see if  this works

Have you turned off OpenCL acceleration?

Welcome to the Serif Affinity forums.
First thing to check: in Preferences, Performance, do you have Hardware Acceleration enabled? If so, disable it, and restart the application, and see if that resolves your issues.

It is gaming that has driven the development and competitive pricing of modern GPUs.
