patch proposed upstream:

Anyway, this minor issue is not worth a backport, moving to 7.2.

I can reproduce this issue with package:
virt-manager-1.1.0-12.el7.noarch

Steps are the same as description above.

Results:
When wrong password was input every time, the screen will flash black and white.
After several times, the console will be black.

Then try to verify with new build:
virt-manager-1.2.0-2.el7.noarch

Steps:
1. Install a guest with spice display server and set the spice password with "aabb";
2. start the guest and try to open it with virt-manager
# virsh start $vm
# virt-manager
double click on the guest item
3. the password dialog will come out, now input the wrong password like "a",
and confirm by click "Enter" quickly
4. the password dialog will come out again, repeat step3 quickly about 10 times.

Result:
1. After step 3, the screen will not flash.
2. After step 4, The console will not be black.

According to the result stated above, move this bug from ON_QA to VERIFIED
