my cursor flicker rapidly

in my TUXEDO InfinityBook Pro 15 v4 processor= Intel Core i7-8565U, RAM=32Gb, graphics card Model: “Intel UHD Graphics 620 (Whiskey Lake)” using 15.1 didn’t happen, but using 15.2 (KDE Argon) my cursor flicker rapidly when I move it, is there a solution?

Please show us the output of

inxi -Gxx

*You may need to install a package of the same name first.

You could try testing with the following kernel parameter (added to grub config)…

i915.enable_psr=0

here is:

pla@pla4-TW:~> inxi -Gxx

tried with

i915.enable_psr=0 after the line "splash=silent resume=/dev/disk/by-uuid/551fc2e6-1664-473b-ba77-495bc9bbbed7 quiet mitigation=auto"

but doesn’t works, it seems that lines goes across the cursor expecially when it is on tabs in dolphin or firefox

You need to place i915.enable_psr=0 within the quotes.

"splash=silent  resume=/dev/disk/by-uuid/551fc2e6-1664-473b-ba77-495bc9bbbed7 quiet  mitigation=auto i915.enable_psr=0"

I did again now, I booted and selected leap 15.2, pressed “e”, edit grub parameters adding after

splash=silent

the

i915.enable_psr=0

getting

splash=silent i915.enable_psr=0 resume=/dev/disk/by-uuid/551fc2e6-1664-473b-ba77-495bc9bbbed7 quiet  mitigation=auto

but didn’t works, the flickering remain.
I also modified parameters in system settings>display configuration>compositor but the flickering didn’t disappear.
suspecting that kwin could be the responsible I also passed from leap 15.2 KDE argon to 15.2 standard disabling the KDE argon repositories and performing a

zypper -v dup --allow-vendor-change

so, now kwin is version 5.18.5-lp152.1.3 (the kwin in KDE argon was 5.19.4-lp152.364.1) but the flickering doesn’t disappear.
15.2 with flickering is nearly unusable :expressionless:

Which cursor theme are you using?

Have a read of this thread…
https://www.reddit.com/r/kde/comments/hkkjj3/bug_plasma_5_mouse_cursor_flickers_when_changing/

also me red that, I used many cursors theme, now oxygen yellow, before also breeze and also DMZ as the article says, but nothing change, furthermore my cursor blink also when it is stationary and non only when change as the article, I also tried to do this with a .sh script in /etc/profile.d/plakwin.sh

export KWIN_TRIPLE_BUFFER=1

as red in another article, didn’t try KWIN_FORCE_SW_CURSOR becouse it seems to be for wayland, other differences are that in the article is used nvidia and me has “Intel UHD Graphics 620 (Whiskey Lake)” , with leap 15.1 everything is ok

also me red that, I used many cursors theme, now oxygen yellow, before also breeze…

Ok, we cannot possibly know what you’ve read/tried etc unless you disclose it here. It’s clear to me that most users are not experiencing such an issue , or we’d see many more posts like this. In any case, from what I have read so far, it seems to be limited to particular Intel chipsets, and I can only suggest a bug report.

manythanks deano, saying many cursor themes I intend that I tried the standard ones and many others but no change in the behaviour so I suppose it doesn’t depend on cursor themes.
now I tried starting a “plasma full wayland” session and the flickering disappeared, but firefox shows most of the windows black and brave didn’t start, so I tried “plasma wayland” and until now everything seems to works and the flickering disappeared, I don’t know the difference between full and simple wayland but it seems that non full works better, I will file a bug report I don’t know if in opensuse or kde

…it doesn’t works, the flickering disappeared but wayland crashes and send me directly to login after 5 minutes, telegram desktop doesn’t works

Report upstream, KDE.

BTW, read the following post for a good summarisation about KDE (Wayland) and KDE (Full Wayland)

I’m trying with gnome and flicker less, much lesss but flicker, in firefox and other browser and mainly on tabs…

there are two GNOME sessions on my login screen, one flicker the other not, how can I get the differences between the two?

I assume that you’re referring to Gnome (Wayland session) and Gnome with X11 session…
https://doc.opensuse.org/documentation/leap/reference/html/book.opensuse.reference/cha-gui-desktop.html#

Within the session you can check using…

echo $XDG_SESSION_TYPE
echo $DESKTOP_SESSION

I have an intermittent rapid-flickering problem when starting some applications (e.g. LibreOffice), and drop-down menus are occasionally completely black until the cursor is moved into the field. I’ve also previously reported a problem where the window buttons (park, full-screen, dismiss at top right) sometimes go black until the application is restarted. And finally, I have a possible need for interactive X-windows sessions over a LAN.

What is the current state of Wayland in Leap 15.1? Is it worth trying, and how is it enabled? Are there any big disadvantages?

It continues to be work in progress, and you’re probably best just to appraise it for yourself. Gnome (Wayland) is making good progress, and usable for many. A good summary in this archlinux page and also this Gnome (Wayland) page.

I do have the same issue.

when I am on KDE, menu items of Opera, Vivaldi, LibreOffice the cursors flickers and gets invisible.

hovering over Dolphin it doesn’t
I am now on a new Ryzen7/VEGA notebook with the radeon drivers.

I didn’t experience this using Intel/ Nvidia open source driver.

Also switching to Plasma Wayland did help, while full Wayland has continuous application crashes.
