[nvidia] GNOME3 notification background layer paints over notification text if mouse is moved in notification area

[Armand Bozsik]

Hello,

I do not know if it is a problem of the current proprietary driver or xorg or GNOME. I tried my best to include all the info you might need.

Problem:

When I receive a notification in the notification centre of GNOME, it shows up in the notification bubble. If the text in the notification bubble is longer than the amount of text can be shown at once, the it needs to be opened. If I click on the bubble, it opens, but if I move my mouse pointer inside the said notification the light greyish background color of the notification area paints over the text rendering it to be unreadable. If I wait some seconds then this 'layer' disappears partly or completely.

Since my VGA works fine under heavy load (GPU intensive applications and games) I guess it is a software related bug

Can you please attach a screenshot or photo of the problem?

[Armand Bozsik (armandbozsik)]

Thanks for your response.
Sure, it can be seen here: https://imgur.com/a/8Cnu0hl

[Daniel van Vugt (vanvugt)]

Thanks. It looks like broken damage tracking, maybe relating to a software cursor? Though I'm not sure why you would have a software cursor when the graphics driver is working properly.

"Though I'm not sure why you would have a software cursor when the graphics driver is working properly."

How can I verify I am using a software cursor? And if so, how can I disable that?

Thanks!

[Daniel van Vugt (vanvugt)]

You can't tell, if it's working properly. You also can't disable it because a software cursor is only used when the hardware cursor doesn't work. The only other alternative would be no mouse pointer at all :)

"Though I'm not sure why you would have a software cursor when the graphics driver is working properly."

Can we say that this problem is not realted to xorg or gnome3 and it is caused by a driver bug?
Then maybe a newer driver version can solve my problem... I have found 440.48 in graphics-drivers ppa. :)

[Daniel van Vugt (vanvugt)]

If that driver version solves the problem, yes. If you are willing to risk trying pre-release drivers then please do.
