--- Comment #3 from ajduck@outlook.com --- I have figured out the cause of this.
It turns out this isn't a Wine bug. Wine is working correctly. It's to do with Windows/DOS file attributes.
----
So basically what I was doing was adding my own .png files and putting them in the plugin database folder. Partially this was out of necessity, because some plugins don't correctly get screenshotted in FL Studio's plugin picture making feature (namely ones that use the graphics acceleration, this I believe is possibly a Wine bug) and so I had to make my own screenshots of them and then crop them.
FL Studio's own plugin picture making feature takes a screenshot of the plugin and creates a .png of it. But what it does when it saves that picture is not immediately apparent: it adds DPI information to the png attributes and it also adds Archive and Hidden attributes to the file.
The first one I found out because when I was adding my own manually screenshotted and edited images to the plugin database folder my images were showing up way too big in the plugin database compared to the already included images with a similar resolution.
But the second one was not as apparent because by the time I realised the issue with the images not hiding in the browser I had already applied the "workaround" I stated in the last comment (using a separate Images folder and then hiding it). I realised there was possibly some missing attribute when I used FL's "Add [plugin] to plugin database" feature which automatically screenshots a plugin and adds it into the plugin database/browser and the .png FL created was appearing correctly. Eventually (thanks to using exa as a replacement for ls) I found out about extended attributes and that there was extended attributes to the files FL was creating.
As said earlier, FL adds the Windows attributes "Archive" and "Hidden" to the .png file. Wine/GNU+Linux environments represent this using extended attributes:
user.DOSATTRIB="0x22"
With "0x20" being Archive and "0x2" being Hidden. If the .png file doesn't have this attribute it will show up in FL's browser.
----
So if you're doing something similar to me, making manual screenshots of plugins in order to workaround the FL screenshot bug with graphically accelerated plugins, you need to add this extended attribute to the file (the escaping of the quotes is necessary as the value needs to be a string):
setfattr -n user.DOSATTRIB -v '"0x22"' File.png
To check the file now has the attribute:
getfattr -n user.DOSATTRIB File.png
Anyway, this issue is not a Wine bug. It's a weird thing FL does that's not obvious, especially in a Wine environment. Mystery solved.
Thank you to the Wine team for your ongoing work!
