pretty strange behavior. i searched the net, and apparently Qt (= daz studio = plugin framework) suffers from a similar bug in their own code editor application (mostly on mac, but for a few ppl also on windows). i only found a few things to try, that might bring the cursor back:
- press ESC (after it gets hidden)
- right click somewhere
- ALT-TAB forth and back (however you do this on a mac keyboard
)
apart from that someone wrote that switching to another mouse cursor theme helped.
i don't think i can do much in the plugin code about that problem; apart from all standard stuff, there is only one a bit special function, when the viewport gets opened, that might trigger this - but it's the only way to have the render viewport staying on top of DS; otherwise it would go under the DS window (or any other pane in there), as soon as you click somewhere else.
i'll try to explicitly set a default mouse cursor shortly after the viewport was opened, maybe this helps...
