Hi Ross,

I test the btop application in a4 and I see a slow in rendering:

I have plans to rewrite the screen buffer support and I hope that that improves the rendering performance.

Hi Ross,

I done a little test with perf top tool and this is the result running btop inside A4 and outside, as you can see the most CPU usage are caused by this 3 functions: image

FYI the full are there (up btop inside A4 - down btop outside A4):

can this be useful for you to investigate if the slow rendering is caused by buffer or depends on something other ?

Many thanks for your work and Happy New Year !!!

I tried out a4 with my LazyVim config, and I can also confirm that the character rendering is very slow and (CPU) resource demanding. On the contrary, I found that tmux's character rendering was the most performant. Is there a way to just copy and paste tmux's character rendering code into a4 ?
