Mouse's cursor size is not applied after reboot

[pasman1]

In Lubuntu 21.10, changing cursor size in Preferences->LXQT Settings->Mouse and Keyboard->Cursor page works only until reboot. Setting is saved to the file session.conf,
but cursor size is default. Link to the screenshot: https://drive.google.com/file/d/1UZ9bW37_lUZIAfG1c7XeGLooSY8o-1Se/view?usp=sharing

Booting a live *jammy* system on
- dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)

I made changes using LXQt.Settings -> Keyboard.and.Mouse.settings and they are saved as expected in ~/.config/lxqt/session.conf

logout the session & login back in

The changes saved in file are still present.. including the change I made in mouse.pointer/cursor changed from 'breeze' to 'breeze light' HOWEVER

size I'd changed to 32 & 40 in different attempts but it returns to 21 after login in the window, with the 21 reflecting the size of the pointer/cursor more accurately than my attempts of 32 or 40.

For me the change in pointer.size returns to 21 (on this box) visible by the setting in the LXQt.Settings->Keyboard.and.Mouse.Settings window on this live system on logout/login.

Confirmed.

(switching out openbox & using xfwm4 made no difference)

testing on an impish actual install on d755-5 gets mixed results.. but the issue is there on
- dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)

What is clear is I don't use that option, as behavior isn't working as I'd expect it to, however that is not unique to Lubuntu.

I booted opensuse tumbleweed (2021.11.07; LXQt 0.17.0) on
- hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)

and the mouse pointer/cursor size was changing as I expect it to (after logout/login), BUT on that box the selected DMZ(White) cursor was changing to DMZ(Black) each time.. ie. impact was different; but an issue was still present.

I'll continue to explore (I'm hoping to find pattern, then ideally why..)

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

I'm getting again what I'd describe as strange/unexpected behavior on Fedora 35 (LXQt 0.17.1)

Using 'tuxcursor' with a saved size of 30; on logout & login the XQt.Settings -> Keyboard.and.Mouse.settings window is returning to 21 on
- hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)

however the cursor size appears to vary depending on the window I'm over.. It's smaller (21?) over LXQt but larger (30?) over GTK3 windows?. My Fedora & OpenSuse both use openbox & equiv. setups to Lubuntu (for comparison purposes)

Switched (Fedora 35) to Breeze(light/snow) & size 32 & logout/login & on re-opening the window it shows size=21 which is closer to the size reflected.

What I did notice; is some changes are not effective; I suspect the mouse pointer/cursor can be only specific changes despite single-digit changes; but my results varied exploring this.

I believe this is a LXQt bug ; possibly https://github.com/lxqt/lxqt/issues/953
