Updated today to 22.04 and started noticing this issue as well. easy to reproduce when chrome have video or any kind of animation happening. If there are only static pages (like text). There are no lag. This affects all window dragging.
* terminal * files * other apps * also chrome itself Once chrome tab with animation/video/charts is closed or no longer active, everything start working fast again. Only interesting err from journal: ``` google-chrome-beta.desktop[5530]: [5695:5695:0507/003622.561907:ERROR:shared_image_manager.cc(228)] SharedImageManager::ProduceSkia: Trying to Produce a Skia representation from a non-existent mailbox. ``` -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-418 in Ubuntu. https://bugs.launchpad.net/bugs/1799679 Title: Nvidia driver causes Xorg to use 100% CPU and huge lag when dragging OpenGL app windows Status in Mutter: Unknown Status in metacity package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-390 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-410 package in Ubuntu: Won't Fix Status in nvidia-graphics-drivers-418 package in Ubuntu: Won't Fix Status in nvidia-graphics-drivers-510 package in Ubuntu: Confirmed Bug description: Nvidia driver causes Xorg to use 100% CPU and shows high lag and stutter... but only when dragging glxgears/glxheads, or any window over them.
