@BrunoQuaresma — please take a look.

Sorry, but I'm not seeing the issue. Can you please guide me to where is the visual glitch?

Hi @BrunoQuaresma ,

for further information I'm using Egde on Windows and Google Chrome on Linux. On both browsers this happens.

Here is another example:

What command are you running to see these outputs?

I've started midnight commander. But it is the same in bashtop (first screenshot). I tried to downgrade to v0.23.7 but database migration fails so I can not switch easily back.

I'm not a FE developer. Let me know if I can provide some useful information.

Here a screenshot from lazygit.

I think this is good enough, thank you!

Looks like it is a bug on xterm since the line height is "self calculated". cc.: @code-asher Maybe it was introduced in the latest Dependabot upgrade. Is it something you can take a look at?

This seems not be be a new issue. xtermjs/xterm.js#475

Thanks for letting us know @MrPeacockNLB

Interesting, seems to be a bug in the DOM renderer.

My guess is the default renderer in xterm switched from canvas to DOM so we should explicitly set it back to canvas. I thought we were using DOM explicitly before but that was just for a test so I was wrong, we were actually just using the default which was canvas (I just tested to be sure).

Does it look better when using canvas?

Yup, no spaces with canvas, just solid lines.

I've also noticed some performance Issues. Espacially when typing text in WebTerminal. Maybe they are related to DOM as well? Not sure...

Nice to hear that switching back to canves fixes line drawing!

I bet you are right, from my recollection the switch to canvas was largely motivated by performance.
