Firefox: number card leaves a graphics artifact in builder #131

Closed KatieWoe closed 3 years ago

KatieWoe commented 4 years ago

Test device Dell Operating System Win 10 Browser Firefox Problem description Found during https://github.com/phetsims/chipper/issues/840, however it happens in both versions and in master. Couldn't seem to reproduce in Chrome or in the published version in Firefox. When sending things through the function machine, sometimes a bit of the outline of the box will stay behind. This is temporary and goes away on its own. It also seems random, but may increase if things are sent through quickly. Using a longer machine may also help reproduce.

@KatieWoe I could probably dig them out of phetsims/chipper#840, but could you please be specific about "both versions" in this issue?

https://phet-dev.colorado.edu/html/function-builder/1.2.0-dev.1/phet/function-builder_en_phet.html and https://phet-dev.colorado.edu/html/function-builder/1.2.0-dev.4/phet/function-builder_en_phet.html First has mipmaps, second doesn't.

I asked @KatieWoe for clarification of FF version on Slack. She was testing with FF 74.0. I had FF 73.0.1 installed on macOS 10.15.3, so tested with that first and could not reproduce. After upgrading to FF 74.0 (latest), I can reproduce on macOS. So this issue appears to have been introduced in FF 74.

To reproduce:

  1. Start sim
  2. Go to Mystery screen
  3. Select 3-function builder
  4. Rapidly drag cards into builder's input slot

This issue is barely noticeable and doesn't impact usability of the sim. I'll leave it open to see if it goes away in a future version of FF. But I recommend that we eventually close as "won't fix".

I'm also removing the bug label. This is not a bug, it's a rendering artifact that we currently have no control over.

This is no longer a problem in FF 88.0.1. Tested on macOS.

Closing.
