Open Bug 1572253 Opened 3 months ago Updated 2 months ago

Console messages are slow to reflow


(Core :: Layout, defect, P3)





(Reporter: Harald, Unassigned, NeedInfo)


(Blocks 2 open bugs)


Follow up from bug 1571644, see STR for the scenario.

:dholbert recommended to file a bug to investigate the reflow performance for Console in

Dan's profile: , reflows taking 100-200ms

Note that the reflow on hover was fixed in Bug 1571349

The issue can be still triggered by simple switching away and back to the Console

  1. open a first tab on (this page contains ~2000 CSS warnings, CSS warnings seem much heavier to render than normal messages)
  2. Switch to Debugger and back to Console …

AR: 500ms+ reflow delay

moving to layout as people in the team might have a better idea what's happening and if this can be fixed

Component: General → Layout
Flags: needinfo?(pbrosset)
Product: DevTools → Core
Priority: -- → P3

Yeah, I'll try. Toggling needinfo to hopefully remind myself.
