Hello all, and congrats to the CodeWeavers team on their continued work on this incredibly important product for the Linux app ecosystem.
I was wondering if anyone else had experienced this visual glitch when it comes to any version of Office, starting with 2013 and newer. When switching workspaces away from an Office app and back on a GNOME desktop, the drop-shadow behind the window appears corrupted and floats above all other windows. The problem goes away as soon as you focus the Office window, un-focus it and then focus it again, but will reappear the next time you switch away from the workspace and back.
Here is a demonstration of the issue: Link
I presume it has perhaps more to do with Mutter (GNOME's window compositor) that CrossOver may not be able to fix, but does anyone know of a workaround or a way this could be fixed?
Background info for posterity: Office 2013 and onwards changed the window borders so that the drop shadows around the application are technically entire extra objects of their own (hWnds), and not part of the main application window - that's why when you drag the window around, the shadows can often lag behind it, because they're not actually attached to it. Disabling these from being displayed would work around the problem, but there is no user option in Office to do that - even using registry tweaks to disable window shadows in Windows itself, won't disable these Office window borders.
This (archived) link explains the behaviour and while it also confirms that the shadows can't be disabled via user preference, it may clue in to possible hacks that may be used to disable them by force at runtime.
