UI and mouse seems visually lagging like frames are dropping.

What version of Parrot are you running? (include version (e.g. 4.6), edition(e.g. Home//KDE/OVA, etc.), and architecture (currently we only support amd64)

What method did you use to install Parrot? (Debian Standard / Debian GTK / parrot-experimental)

List your hardware specs to include make, model and firmware (when applicable):

If there are any error messages or relevant logs, post them below:

If your dmesg output shows a line like:
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
It is an i915 intel drv bug. Mitigation is adding intel_idle.max_cstate=4 i915.enable_psr=0
as boot param. Might not work for all Laptops. There are some reports that Lenovo Ts still have Problems. But the bug reports had Razer Outputs listed, so it might work. Because of the boot param Mitigation they dropped the bug to medium :roll_eyes: So it may be out there for a while.

I found the issue, Bluetooth mouse was causing it, its fine now.
