Comment 2 Maarten Lankhorst 2019-06-07 11:08:04 UTC

User impact: Cursor will be laggy when the system is active (page flips occur). At least on a dual screen config.

Comment 3 Lakshmi 2019-07-31 08:18:06 UTC

Occurred only once and there is no new instance captured in CI bug log. Wait for another month close this issue as WORKSFORME if there is no new failure.

Assigning to myself.
