I am still having this problem with newer versions of all kinds of things and even a new video card (of similar type).
Current video drivers etc.: -Display- Resolution : 1920x1080 pixels Vendor : The X.Org Foundation Version : 1.20.13 Current Display Name : :0 -Monitors- Monitor 0 : 1920x1080 pixels -OpenGL- Vendor : X.Org Renderer : AMD JUNIPER (DRM 2.50.0 / 5.4.0-90-generic, LLVM 13.0.0) Version : 3.1 Mesa 22.0.0-devel (git-df92a13 2021-11-09 focal-oibaf-ppa) Direct Rendering : Yes -Extensions- Composite DAMAGE DOUBLE-BUFFER DPMS DRI2 DRI3 GLX Generic Event Extension MIT-SCREEN-SAVER MIT-SHM Present RANDR RECORD RENDER SECURITY SHAPE SYNC X-Resource XC-MISC XFIXES XFree86-DGA XFree86-VidModeExtension XINERAMA XInputExtension XKEYBOARD XTEST XVideo XVideo-MotionCompensation default screen number: 0 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1885246 Title: Desktop freezes when moving window fast to other desktop Status in lightdm package in Ubuntu: New Bug description: For a long time sometimes my desktop freezes suddenly and it took me a long time to find when. It turns out sometimes the desktop freezes when I move a window fast from one desktop to another, normally I would move it to the right. OS is Ubuntu 18.04 and the issue occurs (as far as I remember) with the Open Source drivers and the AMD drivers. When using some default setting/driver the issue does not occur, but then screen updates are very slow. I am using an MSI H81M-P33 motherboard, processor i5-4460, AMD Radeon HD 7700 Series (according to AMD driver). Monitor is AOC 1920x1080. I tried many things, like different kernal versions and different drivers. The currently installed AMD drivers don't work with the 5.3 kernel. I did not recently use something like kernel 5.0, so I don't know if the issue is solved in later kernels. I found some similar reports, but they all or mostly seem to relate to laptops. While writing this report my desktop crashed again and I was not moving a window, but just resizing it from the top down. I can access the system through ssh and just changed the drivers from AMD pro to AMD open source. Not sure what the effect is. More details available if needed. I would appreciate this would be solved, as it is pretty annoying to restart my computer several times a day and sometimes losing work.
