Screen not cleaning on 3.0

[PolCPP]

• [x ] I am on the latest Hyper.app version

• [ x] I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: Windows 10.

• Hyper.app version: 3.0.0 (stable)

• The issue is reproducible in vanilla Hyper.app:

After updating to 3.0 Stable, (also happened previously on all the canary versions, just didn't bother to report it) both clear on bash or cls on cmd don't work correctly. I don't think this is a duplicate of #3147 since i never had problems with it on the 2.0 branch.

It happens randomly, sometimes it clears sometimes it doesn't, sometimes it clears partially like on that screenshot.

This issue previously only occurred on resizing for me in WSL but now occurs whenever the buffer for the screen is changed in any way.

Can be reliably reproduced by just running ls; clear in WSL

[jcolesio]

I'm currently seeing the same thing.

[Melanpan]

Same happening here. Sure is a step up from the bug where a line was getting cut off at the bottom /s

[Machine-Maker]

Yeah, same thing is happening for me as well. Usually just clicking on the screen a few times clears it up.

[mhall]

This is an especially bad problem when using applications like vim or tmux which draw status bars.

[snassour]

when I click on the screen after writing clear, it clears the terminal, but this is not convenient

[Glenn-Jaya]

I'm having the same issue. I'm using git bash as the shell in windows.

[Glenn-Jaya]

To quickly get rid of it, for now I do "control =" and "control -" to zoom in and out and it gets rid of it.
Until it happens again.

The same problem here, so far has anyone succeeded?
i managed fix my configurations by following #3605
also, restore configurations file by default solving the clear problem, but when shell environment is changed to bash the clear problem returns.

Seems like the only viable fix for now is to:

• block hyper from auto updating
• downgrade to the latest 2.x.x release available
• wait until all 3.0.0 related bugs get addressed

[MarxSoul55]

@azefiel I agree. Judging from all the issues that have been popping up, I think v3 was rushed a bit. Downgrading is definitely a reasonable move.

See: #3604

[miklevin]

Same problem here. Clear only clears part of terminal and varies with number of lines cleared on each re-run.

The cygwin env solution and webgl true solution don't work for me either. I'm on version 3.0.2.

The Ctrl + followed by Ctrl - solution does work but is tedious.

[fluoridepsychosis]

same shit here really annoying

Bad, bad timing with WSL 2 and Windows Terminal dropping later this month.

[WeslyG]

• windows 10 1803 - all work currently
• windows 10 1809 - all bad :(
• window 10 1903 - i am update my pc...

[WeslyG]

And yep, i am update to 1903 my windows 10 and this bug disappeared.
hyper 3.0.2 + WebGl

[MarxSoul55]

@WeslyG Good to know! Has anyone else gotten this fixed by upgrading to 1903?

[MarxSoul55]

UPDATE:

I'm now on Windows 10 v1903. I installed Hyper 3.0.2 (after uninstalling my previous version of 2.1.2) and ran Debian within WSL (WSL 1, not WSL 2). I ran into the bug again, however, I managed to fix it by setting webGLRenderer within .hyper.js like so:

webGLRenderer: false

So essentially the fix was a combination of 1903 + this config setting. Did this fix it for anyone else?

EDIT:

After some more testing, I found that when using nano, the bottom bar is not cleared from the terminal. Suffice to say, this fix isn't comprehensive, unfortunately.

[hakanersu]

Windows 1903 with Hyper 3.0.2 and webGLRenderer not fixed my problem.

[MarxSoul55]

That's unfortunate. I would try to investigate more into this issue myself, but I'm a little short on free time. If anyone else comes to a solution, please let us know.

As a side note — I think it's a little concerning that such a basic issue has been open for 2 months now, and that there are several duplicates explaining the exact same issue. It makes me feel like Hyper isn't really being taken care of. I love Hyper, so I hope that isn't the case.

I hope this bug can be resolved, but I'm not sure it'll be anytime soon. In the meantime, I can suggest Terminus, as it doesn't suffer from this issue, and is quite nice overall. I also suggest looking into Microsoft's official terminal as well, although it's still very young.

Cheers!

Has anyone tried my method? This requires a change upstream, and recompile. I wonder if it works for others.

Not really actually they had the same issue for like 2 years... just a little less annoying

[fluoridepsychosis]

Terminus is unbearably slow and bloated even for an electron program

[MarxSoul55]

@PolCPP Ah, I didn't know about that, since I don't use git-bash. With regular bash, it works fine, at least for me. Regardless, thanks for the heads up! 👍

@fluoridepsychosis To each their own, I suppose. I haven't had any issues with bloat/speed, but then again, I'm fortunate enough to have a beefy machine.

@XinRoom Interesting! I'll have to try this out later on when I'm less busy — I'm not sure when that'll be though. Can someone else verify that his method works?

[DeanGalvin]

For reference, this is still an issue. Tried several workarounds found online to no avail.

[JoshuaSmeda]

Just an update: Problem still persists.

You can manually force a buffer clear by running: ctrl shift k but this is not a ideal solution.
