Summary	0001554: Some VST Plugins are not displayed properly on Wine (Linux)
Description	Some VST Plugins don't show their GUI properly on Wine. Usually the GUI is displayed as a black screen. This doesn't happen with all plugins, but it always does with Synth1 v1.13 and S-YXG50. If you click where a button usually would be in the plugin GUI, that button will be temporarily visible, but will disappear after closing and reopening the plugin GUI. This issue affects both the current stable (1.30) and experimental (1.31) builds. I also tested some older versions like 1.28.10.00 and they seemed to be affected as well.
Steps To Reproduce	Run OpenMPT on Wine. Create a new module or open an existing module. Add the Synth1 VST plugin. Open its GUI by pressing the "Editor" button. The GUI will be an empty black screen (If it isn't, it probably will be after closing and reopening the GUI).
Tags	No tags attached.

Has the bug occurred in previous versions?	Probably

Saga Musix 2022-01-27 21:02 administrator ~0005022	This is a limitation of Wine; it's a general limitation when using the plugin bridge, so you will only see this issue with plugins that don't match OpenMPT's process architecture.
