Success: Pianoteq 9 / JUCE 8 working on Arch (CachyOS) with d2d1-dcomp-11.0

[mklnln]

Built the d2d1-dcomp-11.0 branch from source on CachyOS (Arch, rolling), Wine 11.0, new-WoW64 (--enable-archs=i386,x86_64, no lib32 deps), installed isolated to /opt/wine-d2d1. Compiled clean, no patch/build issues.

Pianoteq 9 (VST3, 64-bit) now renders its full JUCE 8 GUI correctly — no black window. Running it bridged into Bitwig Studio via yabridge 5.1.1. Because yabridge uses one Wine binary globally, I use a WINELOADER dispatcher script that routes only the Pianoteq prefix to the patched Wine and everything else to system wine-staging 9.21 — works perfectly, other plugins unaffected.

I packaged it for Arch/CachyOS (source + prebuilt-binary PKGBUILDs, plus a full write-up incl. the yabridge dispatcher) here in case it's useful to point other Arch users at: https://github.com/mklnln/wine-d2d1-dcomp — not on the AUR (registrations frozen after the June 2026 malware wave), so install-from-repo for now.

Just wanted to confirm the 11.0 branch works great outside Fedora and thank you for the patches. Happy to test other plugins or provide build details.

Thanks for the detailed write-up — really appreciate the PKGBUILD and
yabridge WINELOADER dispatcher, that's a useful reference for other Arch
users. And good to hear the 11.0 branch works cleanly on CachyOS with
new-WoW64.

Pianoteq 9 / JUCE 8 is a solid data point — confirming it renders outside
our own NVIDIA / KDE / WineASIO test setup matters. If you do end up
testing other JUCE 8 plugins (or anything else) on that build, feedback
is always welcome, either here or via a new issue.

Out of curiosity, which GPU are you running it on?

[mklnln]

I am running this GPU: Intel UHD Graphics 770 @ 1.50 GHz [Integrated]

[giang17]

Thanks — Intel UHD 770 is actually a really useful data point. Up to now
the external reports were NVIDIA (our own setup) and AMD RADV (5), so
filling in Intel integrated graphics matters: it shows the stack isn't
relying on anything a discrete GPU gives you. Pianoteq 9 staying
responsive on an iGPU is a good sign for the JUCE 8 / D2D1 path in
general.
