Waveform icon issue in Linux/KDE

[elcalen]

So here's a little aesthetic issue that's maybe relatively insignificant in the grand scheme of things, but it still bugs me a little... On my Ubuntu system running KDE Plasma, the Waveform 12 logo shows fine in application menus. However, when I launch it, I very briefly see the icon in the task manager, but then it changes to an ugly generic X11 application icon.

EDIT: I did a little digging, and it seems the issue might be that application name in the .desktop file doesn't match the window class of the launched application. I copied the .desktop file from /usr/share/applications to ~/.local/share/applications and modified the "Name" field to read "Waveform" instead of "Waveform12", and now the icon in the task manager would seem to work correctly...

EDIT 2: Even with the above workaround, however, the icon displayed in the title bar, and when switching windows (with alt-tab, or using KDE's overview view), is still the generic grey X icon...

It's possible to set the title-bar icon with 'xprop', and as of v12 they're trying to do it, but they appear to be setting it on the wrong window (the splash screen is the problem, I think).
