[frameworks-kirigami] [Bug 482035] [6.0] Scrolling is done at a lower framerate than the monitor's
https://bugs.kde.org/show_bug.cgi?id=482035 --- Comment #6 from Naxdy --- Interestingly, my wife (same mouse) doesn't have this issue, at least not to the same extent (it's still present, but weaker). Could be monitor related perhaps? She's on a 2560x1080 monitor @144Hz, I'm on a 7680x2160 monitor @120Hz, both her and me are at 100% scaling. -- You are receiving this mail because: You are watching all bug changes.

Have not tried testing it on my 60Hz laptop though. FWIW it might even be a specific mouse wheel event of your hardware; but I'd assume it's a Kirigami.WheelHandler bug. Mind posting here the mouse manufacturer & model, just in case? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=482035 --- Comment #3 from Naxdy --- Sadly I don't have a way to measure it, but I was able to capture the behavior on video. The file is too large to be uploaded here, so I've put it on my cloud: https://cloud.polskalemon.com/s/DkFnPSdPxT79Dk5 Note that, obviously, this only makes sense to watch on a 120Hz (or more) monitor. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=482035 --- Comment #1 from ratijas --- That's quite unexpected. The new smooth scrolling behavior is backed by a QPropertyAnimation, which is supposed to integrate with QML scene's (and ultimately QWindow's-) refresh rate without any additional setup on our end. The only custom timer I see in this code is the one to force stop the animation after 400 ms. https://invent.kde.org/frameworks/kirigami/-/blob/master/src/wheelhandler.cpp -- You are receiving this mail because: You are watching all bug changes.
