Title:
Unity plugin causes lags in windows movements (multimonitor)
Status in Unity:
New
Status in “unity” package in Ubuntu:
Confirmed
Bug description:
Unity plugin (started after second monitor connected) causes lags in
windows movements.
Steps to reproduce it:
Start ubuntu unity with connected second monitor and move window.
After some research i found that disabling Unity Plugin in ccsm makes
windows moving smooth again even if vsync is enabled in opengl plugin.
But after reenabling unity plugin ... lags.
Also if i start ubuntu without second monitor connected and connect it
after login to unity before running any applications then moving
windows works ok without any lags, but if i start few apps and then
connect second monitor ... lags.
