Bug ID: 108832
Summary: Cursor flickering on switching between cursor types
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: marlock9@gmail.com

Creating bug here because with help of KDE developer I have investigated it is
amdgpu bug.
For example, I'm moving cursor arrow on text. Before it turns to "I" for text
selecting I clearly see the intermediate cursor texture (can't see what type is
it) located right or left from current cursor position. Same when I moving
cursor arrow to the border of screen to resize. It looks like glitch or
flickering.
It's lasting for about 2 years on different distributions.

Above is link to a slo-mo video. You can clearly see what's happening when I'm
moving cursor straight down from text:
1. "I" cursor
2. Arrow cursor appears 5 px left from "I" cursor
3. Arrow cursor leaps to the 15 px right-down diagonal
On the monitor it looks like flickering jumping of cursor.
amdgpu 18.0.1
libdrm-amdgpu1 2.4.91
linux 4.19.0
Radeon RX 570.
So, kde developer said:
"The issue is very likely in the video drivers, possibly not correctly
syncronizing cursor position and cursor shape updates. I suggest to report it
to the developers of your video drivers (your distribution might help to locate
these)."
Finally, I have some experiments with video driver settings and I have no
issues with such options in 20-amdgpu.conf:
Option "SWcursor" "true"
Option "TearFree" "true"
Truly said, only enabling SWcursor is enough for get rid of this bug but right
after appears so much tearing (due to "KMS Pageflipping: disabled because of
SWcursor" I suggest) so I needed to enable TearFree.
