Screen breaks when reading /dev/console

[arbuz]

Hello. I just enter in the Terminal:

cat /dev/console

and see the following behavior: ​https://imgur.com/a/rH3jLm5

"Operation not allowed" - it's ok, there is obviously some kind of restriction, but after this restriction is fulfilled, the system unexpectedly continues to do something, which leads to strange results.

In the video, I'm using VirtualBox for capture the video, but the behavior is the same on real hardware, on an Intel video card.

This is Beta 4.

This is actually the expected behavior, more or leess. /dev/console is the whole-screen text mode console. When it is opened, it clears the whole screen.

I guess since KDL knows how to tell app_server to do a full-screen refresh on exit, that /dev/console should be able to do so as well.
