For a while, the linux client would generate 2 boxes on the screen, and would generally run slowly / poorly.
Now, the boxes are gone, (see the picture, the arrows and lines show where the boxes were)
they were actually being written in the top level display itself.
Now the boxes are gone, and performance is so fast and clean, that I'm impressed and I respect the attention to detail your team has put into this task.
Well done, and thanks.
