Bug ID: 56935 Summary: Softube VST plugins are not drawing their UI Product: Wine Version: 9.12 Hardware: x86-64 URL: https://www.softube.com/ OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: dwmapi Assignee: wine-bugs@winehq.org Reporter: notasas@gmail.com CC: jzeng@codeweavers.com Regression SHA1: f397807415b4807aeabac7243a13a15599008ee7 Distribution: ---
The plugin UI never updates, it's window is cleared with black on startup and then it just shows the remains of anything that was ever drawn over it, like unrelated windows. With the commit is reverted everything redraws normally.
Softube provides a free plugin that reproduces the issue ("Saturation Knob"), but sadly it's not very straightforward to set it up. First you need some DAW software what can run windows VST plugins through wine, like lmms. Then Softube doesn't provide it's plugins directly but insists on installing them through their bloated downloader, which then insists to install several licensing services. I could not get it to work through wine and used a windows vm for that part. Once you get the plugin dll however everything works through wine, including "activation" (even for a free plugin) except that the UI is not updating.
