Window gets black #64

Closed d0iasm closed 2 years ago

When brower-rs.bin is executed on liumos, an application window gets black once it is overridden by a cursor or it is moved.

Thanks for the report! I found that it was a problem about how we are allocating a Sheet buffer for apps: it was pointing a user mode memory region, which is not mapped when we move the sheet, so Flush() copies literary "zero" data that results in a black screen.

Mark as fixed.
