I need to read something a couple of pages back, so I scroll back in the buffer. Then I clear the screen with CTRL + L. Screen is already cleared, but only the visible screen in the middle of scrollback buffer. When content fulfills the whole screen and it starts to scroll, the new output is mixed with previous buffer content. Also scrollback buffer is now messed. I think, that clearing of the screen with CTRL + L should work as in the Linux terminal (e.g. Gnome Terminal). When I press CTRL + L in the middle of scrollback buffer, it just jumps to the end of scrollback buffer. Nothing is really deleted. This way, the whole scrollback buffer is preserved and screen is also cleared. So, clearing the screen doesn't clear anything in the fact. It just scrolls the content up until the whole screen is blank and prompt is on the first line. I think, that these bugs result from different philosophy of working with buffer from the Linux terminal. I could live with that, I just have to clear the screen on the end of scrollback buffer only. But messing of scrollback buffer, when I quit e.g. LESS as I described in my previous post, is really pain. The buffer is messed so many times, how much prompts are on the current screen. When I scroll one page back, screen is repainted with buffer only from bottom to the most bottom prompt (that means only few lines could be repainted, for example), where the most bottom prompt is repainted too. So I scroll one more page back and it repeats, but with another most bottom prompt. Until all prompts on the current screen are repainted. Then it starts to scroll properly.
