Can not see the part replaced with the background color

[eru]

It seems that it can not be seen because the background color is transparent in the part replaced with the background color.
Is there any solution?

Am cleaning up this repository right now so replying, seems like this issue is no longer reproducible on Hyper 3.1.0-canary.4, hence I assume it also works on Hyper 3.0 stable. If anyone can reproduce this issue on Hyper 3.0 stable then leave a comment, but it looks like it was fixed from Hyper's end.

It happened in stable(3.0.2) but was resolved in 3.1.0-canary.4.

Thanks for the information despite the long time since this issue was made, I did some digging into where this issue came from. This seems to have been an issue with https://github.com/xtermjs/xterm.js (the library Hyper uses for its terminal) which was fixed in xterm 4.3.0 (for reference: xtermjs/xterm.js#962, xtermjs/xterm.js#1898, xtermjs/xterm.js#2560 PR fixed this).

Apparently, Hyper 3.0.2 was released on May 10, 2019 which still uses xterm v3 where this issue was present.

Since this was a bug with xterm, I'm not sure I can patch this in the plugin directly or if it would even be worth it, so updating to 3.1.0-canary (Hyper updated to xterm 4.3 in 3.1.0-canary.3) would be best. It's also a far more up to date version than 3.0.2 right now as well, a new stable release looks pretty overdue right now lol.
