Bug ID: 481049
Summary: Screensharing laggy on 1440p display
Classification: Applications
Product: XWaylandVideoBridge
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

Target Milestone: ---
SUMMARY
Whenever I try to screenshare my main monitor (1440p, 155Hz) with Discord
through XWaylandVideoBridge , the stream is very laggy, to the point of
single-digit framerates. I've tried both desktop and web versions of Discord,
it only happens when I choose to stream the entire screen instead of a single
application. If I stream my second 1080p monitor, the stream is fine.
STEPS TO REPRODUCE
1. Start a screenshare of the entire screen on a 1440p monitor
OBSERVED RESULT
Very laggy stream which stays frozen for seconds at a time
EXPECTED RESULT
A smooth screenshare
