I did was ensure that both the swap chain and the device had their BackBufferFormat set to D3DFMT_A8R8G8B8. The old code left the BackBufferFormat unspecified and apparently that meant you could get different results on different graphics cards (according
to the bug report).<o:p></o:p></p>

<p class="MsoNormal">Unfortunately I can’t run D3D12 to verify that UNIFIED or translucent backdrops work with D3D12. This makes me nervous because the D3D9 version relies on some magic; in addition to setting the BackBufferFormat there’s a call to DwmExtendFrameIntoClientArea
over in glass that allows the swap chain to use its alpha channel. It seems to be triggering the logic in the OS that allowed the old Aero glass effect to work. I just assumed the same would apply to D3D12 but I’m beginning to wonder.<o:p></o:p></p>

<p class="MsoNormal">For what it's worth: UploadingPainter is normally used with TRANSPARENT stages which are implemented as layered windows. The pixels are passed to GDI using UpdateLayeredWindow which explicitly supports an alpha channel. KickstartFX is using
UploadingPainter with a non-layered window and expecting the alpha channel to work. I’m not sure the glass code was designed to ensure that; it seems to be working by accident. The bits are passed to GDI using SetDIBitsToDevice and the documentation says
nothing about the alpa channel. I suspect this call is also dependent on the magic DwmExtendFrameIntoClientArea call to make the alpha channel to work.<o:p></o:p></p>

If what Martin mentioned in comment history is correct, there’s a possibility that with D3D12 there should be no transparency issues, as D3D12 defaults to alpha-supported SwapChain buffer (BGRX format exists but presents some technical issues and limitations,
BGRA is more convenient). However I had no way of verifying this theory, on my Intel Iris Xe laptop the reproducer works as expected on both D3D and D3D12, with or without UploadingPainter.</span><o:p></o:p></p>

Not all of them, most are fine. There are no differences in terms of style classes etc. between the labels. When scrolling, the rendering sometimes switches between this corrupted and normal state after some delay.<br>
<br>
After a while I also figured out that text rendering is responsible for the issue of the nodes vanishing: Certain label contents broke the renderer. For example, in my application, the string "Password manager" when assigned to a label broke it and nothing
was rendered anymore. I tried to find an easy reproducer but was not able to. It's probably very dependent on all the different style classes that influence the text shape/size/etc.<o:p></o:p></span></p>
