[BUG] Manjaro Deepin visual flickering after 18.01.2019 update



video-linux drivers before & after update.

I’m 100% positive that before there was no 1 and 2, 3 was partially (there was this transparency lag like on first second to the right, but no flickering)

  1. Deepin file explorer example (flicker to transparent):

  1. Pamac example (flickers to black):

  1. Deepin settings example (noticeable to the right):

1 & 2 doesn’t happen of virtual machines, so must be driver related.

inxi -Fxxz for one of test machines:

Maybe its specific to your system. Issues not present here.


Most certainly it is, or specific to Intel / video-linux combination


Anyone have any ideas?)

Not that i’m a fan of video-linux, but it wasn’t this way before update.

Besides, i would go Intel proprietary, but for some reason Manjaro doesn’t offer them for Intel GM45…Why? Deepin for example offered them and it worked fine.

Just for the test i’ve booted to terminal from grub (appending 3 to the end of linux entry)

  1. Removed video-linux with mhwd
  2. Intall video-linux with mhwd
  3. Reboot

Then 1 & 2 now solved…

But 3 & questions about updates and above still remained…
And now weird diagonal screen tearing in Firefox is back…Dammit!

Hope it will help to debug problem further.


3 (settings) still active after 10.02.2019 update :worried:
