Che: Terminal font excessive spacing in 6.10.0

[bencaldwell]

Description

After upgrading from Che 6.9.0 to 6.10.0 the font in the terminal has excessive spacing (see attached screenshot). There is no setting under preferences to allow changing this back to its previous more readable font setting.

Reproduction Steps

1. Start Che 6.9.0 multi-user in docker environment using docker run -it -e CHE_MULTIUSER=true -e CHE_HOST=${EXTERNAL_IP} -v /var/run/docker.sock:/var/run/docker.sock -v ~/.che-multiuser:/data eclipse/che start
2. Configure and run a workspace, the terminal font is fine.
3. Upgrade to to Che 6.10.0 using docker run -it --rm -e CHE_MULTIUSER=true -e CHE_HOST=${EXTERNAL_IP} -v /var/run/docker.sock:/var/run/docker.sock -v ~/.che-multiuser:/data eclipse/che-cli:latest upgrade
4. After restarting the previously created workspace open a terminal and the font is changed to excessive width

OS and version:

• Ubuntu 18.04 LTS
• Docker Server Version: 18.03.1-ce
• Che 6.9.0 upgraded to Che 6.10.0

@bencaldwell does it happen on the latest nightly version?

[bencaldwell]

@eivantsov yes I've just tested and it happens on the latest nightly version.

Reproduction steps

1. New install of che on a new docker host docker run -it -e CHE_MULTIUSER=true -e CHE_HOST=${EXTERNAL_IP} -v /var/run/docker.sock:/var/run/docker.sock -v ~/.che-multiuser:/data eclipse/che:nightly start
2. Create a new default workspace using the che provided quickstart Java stack
3. Terminal font is still strange as per original screenshot

Same here. I am using Brave and Firefox, the result is a weird-looking serif font being forced into monospacing shape. I am using macOS High Sierra.

[benoitf]

I reproduce the issue with Chrome and Firefox on macOS High Sierra

@AndrienkoAleksandr , any workaround till you fix this issue? Or can I downgrade the CLI version?

[ghost]

@abhinavprateek can you reproduce the issue with 6.9.0?

[abhinavprateek]

Unable to downgrade the CLI version. Couldn't find any documentation to do
it. Can you please guide?

@abhinavprateek you may start Che with a different local data folder and use 6.9.0 tag for eclipse/che image

[KOSSOKO]

@eivantsov, please, could I know if this issue will be corrected soon or I have to downgrade my che version ? Thanks

[ghost]

@KOSSOKO the thing is that I have hard time reproducing it on my Fedora machine.

[sathibault]

Version 6.9.0 does not have this issue for me. I used browser inspection to compare the terminal windows between the working 6.9.0 version and the non-working 6.10.0 version and found that terminal windows in version 6.10.0 are rendered using a canvas object and 6.9.0 is using html dom elements.

We have downgraded to 6.9.0 but that version loads really slowly compared to 6.10.0, so I hope to be able to get back to 6.10.0.

[AndrienkoAleksandr]

I stable reproduced this issue on the virtual machine. I will take a look.

[skabashnyuk]

I have the same issue on
macOS 10.13.6
Chrome 69.0.3497.100

[celevra]

same here on 6.12

[buggtb]

Yeah sad times, its just about usable but makes my eyes bleed. Hopefully that merge works.

[AndrienkoAleksandr]

Should be fixed for CHE 6.13.0
