OSX: Buffer scrambled when scrolling with ctrl+d, ctrl+u #1155

Open mk-f opened 7 months ago

mk-f commented 7 months ago

When hitting ctrl+d or ctrl+u to scroll, parts of the screen are not redrawn correctly, giving the impression of deleted lines, please see: https://asciinema.org/a/8iM3kMOYT9oVapCjpVzl83E4N

This seems to be an issue with curses, compiling without curses solves this, but gives me flickering while scrolling instead.

tested with d1eb36c96a5d98b0ea9a4422fbd247261e169fa5 and the project lua/visrc.lua, config.mk:

I thought this was reported before but I can't seem to find a link. I'm not able to recreate locally and I don't have access to a macOS system for testing.

Which terminal emulator are you using? That may help if someone else is able to look into this.

iTerm2, but it behaves the same with Terminal.
