If I set scroll speed down to notch 4 from the left, I still have this effect in virt-manager (1 -> 2 -> 1 -> 2). If I set it to exactly center, the scrolling is still inconsistent, but it's hard to discern a pattern. I opened the bug report listed as a duplicate of this one. In that bug report the reply was: > (In reply to Zamundaaa...) > virt-manager likely only forwards discrete steps to the VM, and those are > broken in KWin with non-100% scroll speed settings.

Zamundaaa, are you aware of a bug report for Qt I can track on this? If not, should I file a bug report for Qt somehow? I note you said "which are worked on for Qt"- I don't know if you mean that its currently being worked on, or that any fix would require work via Qt. -- You are receiving this mail because: You are watching all bug changes.
