Comment 48 for bug 1959747

I am having the same issue with ~25% CPU usage when hovering over the messages list and from what I can observer this is somehow related to the HiDPI monitor I am using (27' LG, 4k)?

OS: Fedora 37
TB: 102.9.1
Nvidia 3060Ti + X11 (Also tested this with an AMD RX 580 and X11 and Wayland - same issue)
Ryzen 5 3400G (4 cores/8 threads)
16G Memory

I have another Fedora 37 system at work (i7-8700 w/ onboard graphics) and a 1440p monitor and here I have no issues at all. I hope this can be fixed in the not so far future - TB is really laggy at this point for me :-/
