Describe the bug / provide steps to reproduce it

I tried Zed on Windows and have seen screenshots of it on Mac so i believe it's a Linux related issue on both X11 and Wayland.
(Note that on Windows after some testing I've noticed the right side consistently being thinner, although it never disappears like on Linux)

The right side of any outline, which should be 1px in length both for popups and hollow cursor outline, doesn't show half of the time.

Environment

Zed: v1.0.0 (Zed Dev 2c1b961)
OS: Linux 1.0.0
Memory: 23.4 GiB
Architecture: x86_64

If applicable, add mockups / screenshots to help explain present your vision of the feature

outline cursor half of the time:

the other half it looks like this (right side thinner):

the exact same goes for hover popups, also always the right side.
(couldn't take any screenshots because it kept on closing)

If applicable, attach your ~/Library/Logs/Zed/Zed.log file to this issue.

I can also see rendering issues with some icons, here's from the inline git blame:

It only happens with some lines.

Edit: Here's the issue on the project panel

this might be due to the zooming logic, at certain zoom levels it actually behaves perfectly as expected, squiggly lines and folding indicators also tend to break but at these levels everything is perfect.

example of one of those zoom levels

Just got this while working on some X11 stuff. It mostly seems to happen with icons.

Edit: Another quick way to see this is with the LSP loading indicator at the bottom:

Could somebody grab a RenderDoc capture of this happening, please, and share?
