SUMMARY
When using nvidia-blob parabolic animation is slow and laggy, but when I disable "Thin title tooltips on hovering" animations goes very smooth.
As far I understand, there is some bug in nvidia-blob, but we can try to workaround it by adding some delay to show tooltip, maybe one second.
Full disabling tooltips for me is not good, because I can not know what application is in dock, if it doesn't use self icon, for example, most games from Steam doesn't show game icon on dock, they uses standart Xorg icon.
I've tried to research how tooltip is shown, but as far I understood, it uses QML to do this. I have never used QML, so it is hard for me

1. To disable tooltips for latte you can right click dock, Behavior advanced swttings, Items, disable option to show tooltips
2. For ideentifying windows and launchers properly, https://userbase.kde.org/LatteDock/FAQ#My_launcher_and_its_window_are_not_associated_correctly_OR_my_launcher_is_using_a_low-resolution_icon.3F

did the proposed solutions help?

Comment 3 r0ck3r 2021-09-12 08:30:27 UTC

Yes, it helps, animations goes smooth, but whithout tooltips I can't see what application I have in dock, if it have not it's own icon and displaying standart Xorg icon. Tooltips are useful for this. But they are laggy. What if we add some timeout to display tooltip? Maybe, one second after hovering? If it will not render immediately after mouse hover, there will not any lag?

working around graphic drivers issue or compositor issues is not what I would prefer. The experience provided is the one intended to if the graphics driver or compositor have bugs they should fix them.
