Window not drawing correctly.

[cinjon]

Description

On a fresh install of emacs spacemacs (on mac os), whenever I open a split pane, the new window doesn't paint correctly. See below for a screenshot. This also happens in other situations, like if I do C-l to recenter.

Reproduction guide 🪲

• Start Emacs
• Open a new pane with C-x 3 for example and the pane is drawn badly.

Observed behaviour: 👀 💔
The observed behavior is that the pane is drawn really badly. It doesn't even always get fixed with redraw-display, like for example in this window while I'm filing the bug.

Expected behaviour: ❤️ 😄
The expected behavior is that it paints properly. I didn't have this issue on my previous computer at all.

what's the font. and what's the terminal emulator you're using

[cinjon]

This is on Mac's default Terminal using Solarized Dark with Menlo Regular 11pt.

does the problem also exist in GUI Emacs

[cinjon]

From a minute of trying stuff, it doesn't seem to be an issue there.

[lebensterben]

that's what I suspected. there's something wrong with your terminal setting. from the pictures attached above, it seems that anti-aliasing is not working.
Note that the font used by terminal Emacs is not what you defined in dotspacemacs but the font use for terminal.

[cinjon]

Thanks, that's helpful. However, I'm having a bit of trouble squaring what is exactly to fix. Are you suggesting aligning the fonts in dotspacemacs with what's used in terminal or changing a setting (somewhere) or something else? I tried a bunch of the suggestions here without success (#1269). I also checked and "Antialias text" is on by default in the terminal profile.

Is there an expectation that terminal is xterm? Right now, it's being declared as ansi.

@cinjon
I could be wrong about anti-aliasing not working. That could also results from image compression...
But definitely I think you can first try to change the font used by Terminal.app to the one defined in .spacemacs
