Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v5.1-rc7 kernel [0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed”, and attach dmesg. Thanks in advance.

Can't reliably reproduce during every scrolling, but it has happened at least 5 times in the past 7 days. Happens in Kubuntu VM-s running under KVM and QEMU (3.1.0) on multiple host machines. This issue only started to happen sometime this month. First these VM-s were running 18.04 so I was hoping that updating them to 18.10 would help, but it didn't. I'm guessing that some kernel update for both bionic and cosmic causes this. Since this bug causes the graphical environment to become totally unresponsive, this has already already cost me some lost data, but very fortunately not much.
