minimize, maximize, close buttons in title bar become invisible

[Jonathan Kamens]

Recently when I go to minimize, maximize, or close a window (I have the minimize and maximize buttons enabled in Tweaks) I discover that the buttons are invisible. I know they're there, just invisible, because I can click where they should be visible and the expected thing happens. If I quit and restart the application in question the buttons become visible again. This only affects some windows (usually just one) at any given time, not all of my windows. See attached screenshots for an example of what I'm talking about.

Your screenshot is of Firefox, right? Have you noticed this issue in any other apps?

[Jonathan Kamens (jik)]

I believe so. For example I believe I've noticed it in the Settings app. I will keep an eye out and confirm here when I see it in another app.

[Jeremy Bícha (jbicha)]

Ok, I believe that's a Firefox issue so I'm marking this a duplicate of a previously reported issue.

There is a recent gnome-control-center bug with one of its pages: LP: #2033658

[Jonathan Kamens (jik)]

I am not able to reproduce this merely by locking and unlocking my screen so I don't think this is the same as #2002624.

[Jeremy Bícha (jbicha)]

Ok, unmarking as duplicate. Locking the screen might be a trigger, but in my case, this issue only happens sometimes.

Seeing this under the most recent build of firefox, and only under KDE's Plasma Desktop. Running under GNOME seems fine. Was fine up until 117.0.1-2 was released into the snap, which enables wayland support for 23.10.
