Full screen mode causing rend3 to crash

[John Nagle]

Wine msg: 0104:fixme:explorerframe:taskbar_list_MarkFullscreenWindow iface 0000000000083450, hwnd 000000000001004A, fullscreen true stub!

Any known info on this? Is fullscreen just broken, or what?

See crash report for Rend3 here: https://github.com/BVE-Reborn/rend3/issues/399

This issue has been seen in the past on Wine, but for games where the source was not available. Here, it's coming from a mockup UI test that Wine devs can download.
Will wait on comments from Rend3 dev before submitting a Wine bug report, though.
