I'm not using the virtual machine anymore so I can't check it right now, but it shouldn't be hard to reproduce if anyone wants to follow up.
Like I mentioned in the linked Chromium bug, this happens in both Virtualbox and VMWare, so this is not specific to either one of them. I can't remember if I ever tried uninstalling guest additions (although I think so). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1897249 Title: Scrolling in Chromium stops working when moving mouse when running in virtual machine Status in chromium-browser package in Ubuntu: Incomplete Status in falkon package in Ubuntu: New Status in qutebrowser package in Ubuntu: New Status in chromium package in Arch Linux: New Status in chromium package in openSUSE: New Bug description: When Ubuntu is running in a virtual machine scrolling in Chromium stops working when moving the mouse even the slightest. Also the first scroll step is always ignored after moving the mouse. This results in a very uneven scrolling which is very difficult to use. Scrolling works perfectly in other applications like for example Firefox. This bug seems to have appeared in Ubuntu 16.04.0, as all Ubuntu releases before 16.04 works correctly, while all releases after 16.04 are affected by this bug. Ubuntu is not the only distro that has this bug, but there are also several distros that are not affected by it. My current testing have shown the following distros to be affected: - Arch Linux - Linux Mint 20 Cinnamon - Manjaro XFCE 20.1 - OpenSUSE Tumbleweed - Ubuntu 16.04, 18.04, 20.04 And the following distros and operating systems are NOT affected: - Centos 8 - Debian 10 (Buster) - DragonFly BSD 5.8.1 - Fedora 32 - GhostBSD 20.08.04 - Ubuntu 12.04 to 15.10 - Windows 10 The fact that there are current updated distros that are unaffected indicates to me that this is probably not a bug in Chromium upstream, but I've not been able to pinpoint whether the problem is caused by something in the Chromium packaged by Ubuntu or some other difference in the system like the kernel or system libraries. I have already reported the bug to Chromium, link to the bug report here: https://bugs.chromium.org/p/chromium/issues/detail?id=1128405. There is also another bug report here: https://bugs.chromium.org/p/chromium/issues/detail?id=1100179 I've already spent well over a week trying to troubleshoot this issue. I'm willing to do most of the work myself, but I really need some guidance as to what are the best next steps in troubleshooting this. Any help would be greatly appreciated!
