Copying text to clipboard from Microsoft Edge causes unresponsiveness

[jmontleon]

If I right click and copy text or use Ctrl-c to copy text from the Microsoft Edge web browsers address field TigerVNC and Edge become unresponsive. TigerVNC then Edge will become responsive again after several second.

I can copy text from the address field normally if TigerVNC is closed. I can even copy text from a page in Edge if TigerVNC is open. Copying addresses from Internet Explorers address bar/field causes no problem.

As far as I can tell it's just Edges address field when TigerVNC is open that causes them both to become unresponsive. I have accept and send clipboard disabled, but the same seems to happen with them enabled.

Sometimes I get strange clipboard behaviour from Excel too (where Excel is running on the same machine I'm running vncviewer.exe from).

It can take two presses of CTRL-C for the text to be copied to the clipboard with the correct formatting.

Looks like another user of VNC had the same issue. My problem also went away when I closed the VNC Viewer down.

There is a new clipboard API available in Windows these days. Perhaps that will resolve this issue.

For reference, the new API is AddClipboardFormatListener() and friends.
