Complex vector stroke styles / decorative fonts cause freeze (Wine D2D limitation)

[pi317]

Description:
I experienced complete application freezes when working with groups of many vector objects, or with decorative fonts generating complex path geometry (e.g. Veneer). In my case, applying transparency triggered the freeze, requiring a system restart.

Environment:

AppImage (latest v3)
Linux Mint, kernel 6.17, X11/Cinnamon
AMD Radeon (radeonsi/Renoir)

What the log shows:

Running the AppImage from console revealed this line repeating hundreds of times:
fixme:d2d:d2d_device_context_DrawGeometry Ignoring stroke style XXXXXXXX.
From what I understand, this appears to be an unimplemented stub in Wine's D2D layer. I'm not certain this is the direct cause of the freeze, but the correlation is consistent and reproducible.
I also tried LIBGL_ALWAYS_SOFTWARE=1 — the freeze still occurred, which suggests the issue may not be GPU-driver related.

Reproduced with:

Group of hundreds of vector objects with stroke styles → apply transparency → freeze
Text in a decorative font with complex path geometry (Veneer) → freeze

Workaround that worked for me: (unsatisfying for professionnel work)

Right-click the group in the Layers panel → Rasterize ("Tramer" in French UI) before applying effects. This eliminated the freeze in my case. Not ideal if you need to keep objects editable, but it unblocks the workflow.
Sharing in case it helps others or points to something fixable. Happy to provide full logs if useful.
