当我在vim滚动使用j,k或鼠标滚轮这是非常敏感和快速,但只要我打开分屏滚动一个新的缓冲区变得很慢/延迟.即使分屏中的第二个缓冲区为空,它也会出现在非常大的文件(1000+行)中.
我使用不同的终端重现了这个.我也尝试使用ttyfast,lazyredraw但没有一个改变任何东西.
如果我开始使用-u NONE它是相同的,只是不明显.
在滚动和重绘屏幕方面,使用和不使用分屏运行vim有什么大不同?
编辑:
我刚刚意识到问题只发生在垂直分割中.水平分割工作正常!
EDIT2:
仅使用vi/vim的终端版本显示该行为.一旦我使用与vim相同的配置启动gVim,即使在垂直分割中,一切都像魅力一样.我在其他论坛找到了有类似问题的人.他得到了问题的答案,但不是如何解决问题.答案是:
That's because the application has to repaint the screen rather than actually
scrolling (since it cannot rely on the left/right halves of the display
to scroll at the same rate).

这就是我所做的当它对我来说滚动缓慢时,不一定是因为分割,我会尝试使用:22j而不是j,22可以是任何数字,它让vim进行移位而不是计算每个 的滚动j。
