Hello,
immediately after I have upgraded my system from Fedora 28 x64 to 29
graphics' issue started. Mouse leaves a trail composed of multiple
blinking cursors and sometimes rectangular not-refreshed parts. The more
loaded the system is the more pronounced the issue - the longer the
trail. It's enough just to start moving mouse when system is idle and no
app was started by the user yet, to trigger the issue.
My system is based on Intel Celeron J3160 with integrated graphics
(8086:22b1). Before upgrade to Fedora 29 the issue did not occur.
Recently I’ve upgraded to Fedora 30 x64. The issue remains. I use XFCE
as a desktop.
What I have tried so far:
1. Changing Option “AccelMethod” “sna” used so far to “uxa” in
/etc/X11/xorg.conf.d/20-intel.conf.
The issue was replaced with another - no mouse cursor on primary
display. The cursor was only visible on secondary display.
2. Changing Option “TearFree” “true” used so far with “false”. No effect.
3. Remove "AccelMethod" and "TearFree" from the 20-intel.conf. It didn't
help.
4. Remove 20-intel.conf file. The issue was replaced with tearing.
5. Check if xorg-x11-drv-intel is installed. It wasn't.
6. Gathered inxi output (with removed 20-intel.conf file):
$ inxi -Gxx

7. Changed configuration in the 20-intel.conf to the initial and
gathered inxi output:
$ inxi -Gxx

8. Start Live F30 x64. The problem was not present, but video playback
was a nightmare. I could give spf instead of fps when playing 1080p
movies ;-)
[liveuser@localhost ~]$ inxi -Gxx

9. I have installed LXDE for tests on non-Wayland, non-Gnome sessions.
The problem with mouse cursor is gone. Tearing is present with varying
extent.
In Modesetting DDX (i.e. without 20-intel.conf file) tearing is visible
during web browsing on images while scrolling with mouse. It is also
visible during movie playback especially in scenes with lots of panoraming.
In Intel mode (20-intel.conf without any Options neither AccelMethod)
video playback suffers the same. Web browsing is better. Tearing is not
in the middle of a line, but rather whole lines are torn. As if scroll
speed was not equal among y-axis.
In Intel mode adding TearFree Option does what it says. No tearing is
visible.
I'd like to solve the issue on XFCE, which I prefer.
How can I fix this? I will be thankful for your help.
At first I have started a topic for the issue at LQ:
