slow GUI on Dragonfly 6.0.0

[Fritjof Bornebusch]

Hi,

I just installed Dragonfly 6.0.0 with Lumina on a T460.
One CPU core is always at 100%, even if top shows 0.0% for all processes. The remaining cores (3) are at 0%.

Using a browser is increadible slow. Opening more than 1 tab is nearly impossible. The usage of the cores does not change significantly.

Terminal apps work with normal speed.

Any hints what to do?
