This happened to me too.
Apparently in normal situations (scrolling a window, ...), I was almost
suspecting a hardware bug.
definitly no hardware problem
the follwoing params making things better and stop especially
the lags most of the time, but on the same machine over a long
time was set to "pcie_aspm=force" and all i915 option at 1
"pcie_aspm=off i915.i915_enable_rc6=0 i915.semaphores=0 i915.i915_enable_fbc=0"
i think i have to mention taht VT-d is active in the BIOS and
i was wondering that it was stable because the combination of the
i915 options with VT-d (hardware supported virtualization IO) is
classified to be unstable

Long lag (>5 seconds) while starting LibreOffice
yes, libreoffice is a majonr candidate for lags at startup
the window is frozen
at half-transparency while appearing and nothing else updates
(clock is stuck).
exactly the same happening here on two different machines
with ident hardware
Fully updated x86_64 F16.
Nothing logged by the kernel.
It surely happened with more than one kernel: last time was today
correct, but as said i see currently no way to figure out
what kernel started to introduce this and even if maybe all
of the F16 kernels are affected - dist-upgrade some months ago
