Only 3 lines of SQL visible until you resize the query window

[chrismore]

Issue Summary

A few months ago when viewing a redash query, my entire query window only display the top 3 lines of SQL while the rest is completely blank. I can only scroll within these 3 lines. It looks like a CSS or rendering issue.

Steps to Reproduce

1. Open up any redash query
2. Edit the source
3. View the SQL

Expected results:

Seeing all of the SQL with scroll bars

Actual results:

Only 3 lines of SQL are visible and the rest of the query window is blank. You can scroll up/down, but only the top 3 lines are visible. If I resize the query window vertically (with the two horizontal lines below the save/execute buttons), the expected results happens, but only temporarily. If I refresh the page after resizing the query, the issue happens again. This started a few months ago and I have no clear path to resolution.

Any other info e.g. Why do you consider this to be a bug? What did you expect to happen instead?

Technical details:

• Redash Version: web
• Browser/OS: Firefox Release channel + Mac OSX
• How did you install Redash: Browser based, nothing to install. I tried to log out and back in with no hope.

I've been experiencing the same bug for the last week as well.

Bump, there's at least 2 others in the fx-metrics channel who have experienced this.

@rafrombrc, can you confirm someone is looking at this?

[chrismore]

I also want to note that this is a Firefox-only bug. I do not experience this within Chrome. It could be related to scroll anchoring: https://bugzilla.mozilla.org/show_bug.cgi?id=1519644

[fbertsch]

@chrismore maybe disabling the scroll anchoring will help? Though I think that's nightly-only. If it's available in your config, set layout.css.scroll-anchoring.enabled to false. Let us know if that fixes things.

[chrismore]

@fbertsch it works fine in nightly regardless of the value of layout.css.scroll-anchoring.enabled. I set it to both true and false and the bug isn't seen there.

[fbertsch]

@chrismore thanks for investigating, I couldn't get it to reproduce either.

@chrismore @fbertsch I wasn't able to reproduce this in 65, were you?

[jezdez]

@emtwo @washort I was able to reproduce this a few days ago, but can't anymore. Have you seen this recently?

[emtwo]

Likewise, I cannot reproduce this anymore.

[chrismore]

In Firefox 65, I am unable to reproduce it anymore.

[jezdez]

Turns out this has not been an issue in Firefox anymore but Chrome still has it. Good news is it was fixed upstream via getredash#3412.

@rafrombrc Just to make sure, is this something we should close now or leave open until we've pulled in the change in the next rebase?

[rafrombrc]

Let's leave it open until we merge.

[rafrombrc]

Closing since this has been resolved in firefox.
