On a new Windows 11 machine, merge visible creates artifacts

[Don Samuels]

I bought a gaming laptop with an Nvidia gpu to speed up my affinity work. Unfortunately it is Windows 11. My affinity version is 1.10.5.1342.

When I do a Layer->Merge Visible, I get artifacts created like this:

This renders my use of the new laptop for processing useless. Please help.

I moved the file to my old Windows 10 Laptop and did the merge visible and no artifacts were created.

Sounds like hardware acceleration problems. Try turning it off. Edit->Preferences->Performance.

Are your graphics drivers up to date?

Hi Don Samuels,

RichardMH is likely right with hardware acceleration being the cause, disabling it should solve this issue.

Thanks

While the laptop is less than a month old, and was customized by Xoticpc, so that presumably they got the latest drivers on themselves (as opposed to letting Windows do it), I am going through to make sure there are no updates since the laptop shipped.  I hope this works, otherwise I have to ask if Affinity does not have bugs in the classes they use for hardware accel.

Why not first just try turning off hardware acceleration in the Affinity app?

Because one of the main drivers on buying a laptop with an Nvidia Gforce was to get the hardware acceleration for Affinity.

That's fine, but simply turning off Hardware Accelaration in the application Preferences will prove where the issue lies, and probably give you a workaround until it can be resolved.
