[Qemu-devel] [PATCH] QXL: always show default cursor, even for unsupported chunks

["René Rebe" <rene@exactcode.com>]

Hi,

I was testing a Windows 10 guest with HiDPI scaling which

actually made the cursor disappear and only multiple chunks

warnings being printed.

When the cursor is using currently unsupported multiple chunks, the
builtin-left cursor is better than none.

PS: if TB damages the white-space just let me know, only recently 
started using it, ...
