Window minimize animation flickers and appears in the wrong place in Xorg sessions

I reported this as well, however, they think that it is issue with my device. https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1967471

As mentioned by @vanvugt in https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1967471, i attached lscpi and journal

Status changed to 'Confirmed' because the bug affects multiple users.

Changing the refresh rate on my display seems to have fixed this issue for me.

What refresh rates fail/work?

in my case glitches appear with any refresh rate

I may have found the cause of the problem. if you look, the second animation is actually the animation that gnome shell runs when you minimize windows. gnome shell minimize application to the "activities" button while dash to dock tend to override to bottom, left or right depending on where you put the dock

we need to disable the gnome shell animation and I emphasize that this glitch does not occur in wayland session

In my case, the animation problem was in both the xorg session and the wayland session.
Ubuntu 22.04
AMD rx-460 card.

Here is a screen recording showing the problem https://disk.yandex.ru/i/GdSWT1-LO2i7kA
The monitor runs at 60Hz, the video frame rate is also 60.

Installing the kernel 5.17.5-051705-generic solves the problem in case of use wayland session. With xorg problem still exist for me.

Please try disabling the 'Desktop Icons NG' extension, in case it's related to bug 1966659.

With the extension disabled, there are no problems on both kernels (5.15.0-27-generic and 5.17.5-051705-generic) in the case of the wayland session.

After enabling and updating (I'm not sure if the extension has been updated, but I tried updating it on the page extensions.gnome.org) the extension, the problem disappeared also on the 5.15.0-27-generic kernel.

disabling the extension seems to solved the problem only when using only one window

if i open brave browser and then nautilus, if i minimize nautilus the glitch appears once again

Can confirm the issue on my PC. Ubuntu 22.04, Intel + Nvidia, Xorg.

I can reproduce it with and without ding extension enabled

Sounds like we need to keep bug 1966659 separate then.

Can confirm on my laptop too. Ubuntu 22.04, AMD + Nvidia, 165Hz, Xorg, DING disabled, kernel 5.15.0-39-generic. This is a cosmetic issue but it's really annoying when seeing it in action.

Hi,

I can see "flickering" animation too :
https://i.ibb.co/7WytBXj/anim-minimize-glitch.gif

This is on Ubuntu 22.04, with :

  *-display

This happens ONLY on Xorg.

This happens both while DiNG extension ENABLED or DISABLED.

This happens whatever gnome-shell extensions are ENABLED or DISABLED.

For reference : https://forum.ubuntu-fr.org/viewtopic.php?id=2072646

Don't know if it helps, the only option regarding i965 intel driver to have an influence (among the 3 tested there) on the animation of the Nautilus window is "TearFree".

But the problem it introduces (tearing in Firefox) is far more annoying than the problem it solves (the jolting window minimizing animation).

It seems to happen mostly with Nautilus window.

My findings so far, system configuration attached:

- Occurs with any number of windows open.
- The minimise animation seems more broken than the restore animation.
- DING enabled/disabled does not affect the animation behaviour.
- I agree with the findings of comment #10, as the minimise animation shows multiple flickering frames where a thumbnail of the minimising window can be seen shrinking and moving to the top right hand corner of the screen. The expected minimising animation, where the window shrinks down into the dock icon (set to the bottom of the screen on my machine) still occurs while this is happening.
- The restore animation sometimes (but not always) displays a frame where the errant window thumbnail can be seen above and to the left of the window position, presumably the reverse of the errant 'shrink to top left' minimise animation, but for some reason with less visible errant frames and occurs less consistently.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm having the same problem with the minimize animation. On my computer I recently switched from a Nvidia to a AMD GPU since then I have this problem. Glad I'm not alone.

However my laptop with a AMD GPU runs just fine.

After using GNOME 43 Xorg with Debian Bookworm 5.19, I rebooted into Ubuntu 22.04 Xorg 5.15, did some checks and found out that on my Ryzen laptop this was caused by the amd_pstate scaling driver which lowers the minimum CPU frequency down to 400 Mhz instead of the 1400 Mhz default on the acpi_cpufreq which Debian uses.

Debian (acpi_cpufreq) behaved perfectly on both Xorg and Wayland, so I enabled the amd_pstate scaling driver and this issue came up the exact same way as in Ubuntu: it seems that scaling down to a much lower cpu frequency and then back up all the times can cause some performance penalties and glitches.
To me it's fine because in the Xorg session I disabled the animations and the battery life is noticeably better with the amd_pstate scaling driver, but as usual ymmv!
