Hi,
see screenshot. When zooming in/out or panning, then other random sections of some layers are not getting rendered (it's going through several layers)
If I merge down the layers into one pixel layer, that bug even saves into this layer, so it's not just a visual problem on the screen, it's going deeper.
Hardware Acceleration ON, Windows 11, RTX 4090, yesterday's nVidia drivers 537.42
With HW Acceleration OFF the bug disappears.
EDIT: Okay, after another restart of Photo the problem is not reproducable right now. It looks that the previous session had some memory problem/corruption inside Photo maybe. I had 2-3 big documents with many layers open. As it now doesn't appear with neither HW Acc. on/off, I cannot confirm if it was an acceleration related problem.
