Hi!
We've suddenly got an odd issue with GUI, and I'm not even sure where to start looking. Maybe you've seen something similar and can advice on what could it be?
We use version 3.2.6 and D3D12 and suddenly started getting odd lines near some elements on some PCs: their styles are very simple, most of them are even placeholders still based on your example styles (like those blue progress bars).
I've attached some zoomed in screenshots of these issues. Their exact look seems to depend on screen resolution.
The most "complex" one on the screenshot is the "hamburger button" with 3 lines which got its left side corrupted.

Is this using our D3D12 renderer or a custom implementation?

Are the "odd lines" consistent or do they randomly appear?

Could you grab a frame with RenderDoc?

We use your renderer, but slightly modified.

Turns out the issue has been caused by Nvidia driver update. Worked fine in 566, broken in 572.
It is the weirdest one I've seen so far: on affected PCs a frame captured in RenderDoc produces even more lines when inspecting it and zooming-in. These lines would have been less than a pixel wide in the original resolution!

Obviously it is not related to NoesisGUI, we will investigate it further.
Thanks.

Are you able to reproduce this in an isolated XAML? That way, you could also try using our renderers to see if it happens there as well (in XamlPlayer for example).
