[Intel-gfx] Graphics issue after upgrade from Fedora 28 to 29 - multiple mouse cursor icons

[Przemysław Hołubowski]

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

v: 4.5 Mesa 19.0.5 compat-v: 3.0 direct render: Yes

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 at 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:
