I can't seem to reproduce any such problem with Firefox. Can you please
list the affected apps and maybe provide a more detailed test case?
Although I am reminded of bug 1906792, it's probably different.
** Summary changed:
- Xorg freeze when split screen
+ Apps become unresponsive and lag when multiple windows opened
** Package changed: xorg (Ubuntu) => mutter (Ubuntu)
** Tags added: performance
** Changed in: mutter (Ubuntu)
Status: New => Incomplete

Title:
Apps become unresponsive and lag when multiple windows opened
Status in mutter package in Ubuntu:
Incomplete
Bug description:
When I open an application like Firefox, I split them into 2 windows
and place one to the left and place the other to the right. So each
window gets half of the monitor. The right window gets slow when
clicking and lags for 2 seconds. But the left window is normal. This
happens to all applications when I have 2 windows. (When 1 window
only, even if I put it to the right side of the monitor, it still
works fine, no lag). Thank you!
