¡Hola! Steps: - Type "mozilla" in the awesome bar. - Press the down arrow key a few times. - Press the up arrow key a few times. Results: The item that should have been highlighted becomes white, please see https://www.screencast.com/t/vZ4TeAwZ Expected results: The item is correctly highlighted. ¡Gracias! Alex

Thank you! Nightly 58 x64 20171101220120 de_DE @ Debian Testing (KDE, Radeon RX480). fresh profile: layers.acceleration.force-enabled, gfx.webrender.enabled, (also tested: gfx.webrender.blob-images) I can't reproduce here, but I will try it on Windows in a few minutes. (Your screencast is inaccessible for me due to Flash.)

Nightly 58 x64 20171102100041 de_DE @ Windows 10 1703 (Radeon RX480) I can't reproduce it here either.

0m35s from your screencast is interesting: Everything slips down and search engine icons are out of view. Never had this.

¡Hola Jan! This is a 64-bit Nightly, more precisely Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0 ID:20171102100041 So flipping back the flag for 58. Below the graphics part of about:support in case it is useful. In my case a new window is all white, then black before it renders. Would that be another bug? ¡Gracias!

I'm just a Nightly user like you and am helping with filing, confirming and verifying bugs. WebRender is currently Nightly-only and wouldn't reach Beta 58, if I'm not wrong.

(In reply to Jan Andre Ikenmeyer [:darkspirit] from comment #6) > WebRender is currently Nightly-only and wouldn't reach Beta 58, if I'm not > wrong. That is correct. And yes, please leave status-firefox58 as unaffected; any WebRender-specific bugs are by definition a non-default configuration and will not affect 58.

Can you still reproduce this?

¡Hola Jeff! What's the proper way to turn on Webrender these days? ¡Gracias! Alex
