Description pallaswept 2025-03-05 08:42:26 UTC

SUMMARY

When I log into my PC, normally, the cursor is sitting at the centre of the primary display. Since 6.3, I noiced that the cursor is slightly off centre to the right.

I posted about this on the discuss forum, and another user had noticed the same, but offset to the left.

It seems the initial position of the cursor is offset in the direction of the second display?

STEPS TO REPRODUCE
1. Have two displays
2. Login
3. Observe cursor position before touching the mouse

OBSERVED RESULT
Cursor is off-centre in the direction of the secondary display

EXPECTED RESULT
Cursor is centred

ADDITIONAL INFORMATION

This seems to just be cosmetic but I don't know the inner workings so perhaps it's important, so just letting you know.
Wasn't sure which component this should be filed against, either, feel free to move as appropriate.

I haven't looked as use automatic login by default, but my preference would be that the the mouse cursor is by default on the button that you need to press to verify // accept the password entered (in case you didn't know or wanted to just press Enter after inserting the password.
But I guess being at the center at the screen to be more visible would be ok too.
I can move it myself over that button if I needed, even though it will take a bit of my time.

Sorry, that's probably an important detail I have left out, I also use automatic login. I actually don't know how this behaves with manual login.

So basically, if I reboot right now and then take my hands off, I'm going to be looking at my desktop in 30 seconds, and the cursor won't be in the middle like normal.

I don't use automatic login and it also happens, I'm also on tumbleweed
