Every additional application running on the same workspace slowdowns animations
System setup
- Alt Linux Sisyphus, kernel 5.5, Mesa 20.0.4, Xorg 1.20.8
- Gnome Shell 3.36.1
- HW - HP Spectre x360, Intel 8550U + UHD 620
- Laptop screen and external monitor are both 4K though only external monitor is usually used (lid is closed)
- Happens both in Wayland and Xorg sessions
Bug summary
When fresh Gnome session works smooth animations performance noticeably degrades with every additional application running on the same workspace. E.g. 6 applications running on the same workspace make overview animations laggy, 10 applications make window animations laggy (e.g. close or maximize animations). If I move part of applications to another workspace Gnome starts to work smooth again.
