Have monitor on virtual console, switch to monitor and trigger screen
dump. So far that caused the to be dumped screen been written to the
monitor console, the console was furthermore resized, but all that mess
was left behind once dumping was finished. No we switch to the graphic
console first and restore the monitor afterwards.

I suspect this papers over some QXL bug. SDL has no issues when I
trigger the screen dump from a monitor console that requires no switching.
