Before the upgrade from 15.4 to 15.5 I had more issues regarding the video, in
particular when I plug in any HDMI external monitors were not recognized.
So I added
GRUB_CMDLINE_LINUX=���������i915.force_probe=4628���������
in
/etc/default/grub 
and then 
$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
In this way the external monitors were (not all) recognized but some apps does
not work like VLC and apps for video conferencing where video of those apps
starts to flashing...
If I remove 
GRUB_CMDLINE_LINUX=���������i915.force_probe=4628���������
those apps worked properly but I was unable to recognize any external monitor
via HDMI.

I also tried with backports repo before moving to 15.5 alpha but it's not
enough.
Now, with 15.5 alpha version my /etc/default/grub is:
GRUB_CMDLINE_LINUX_DEFAULT="splash=silent preempt=full mitigations=auto quiet
security=apparmor"
GRUB_CMDLINE_LINUX=""
and when I plug in HDMI external monitors seem to recognize and work but not an
"ACER CB282K" monitor.
However, the VLC problems seem to be fixed, in fact I am able to reproduce
video correctly.
When I use apps for video conferencing, they work but sometimes appear some
line within their window (these visualization issue are confidend to the app's
window), not affecting the whole display.

These issue are persisting also after update and reboot(s).

Reproducible: Always

Steps to Reproduce:
1. Just by plug in HDMI cable.
2. Just by open apps.
3.
