[SOLVED] LM 21 and Mint-Y: Do you get bad window control buttons on GTK-4 apps?

[sebastjava]

I think these needs to be fixed, but I need your help to confirm this. Maybe it is just a bug from my virtual machine. I would appreciate if you could take a few minutes to confirm you get these square, bad looking window buttons on real hardware. On a true LinuxMint 21 installed system, and all up-to-date.

Steps to reproduce
1. On LinuxMint 21, in your Themes chooser, select Mint-Y applications theme (GTK theme).
2. From your terminal, install this package for GTK-4 testings:

Code: Select all

apt install gtk-4-examples

3. In your menu, find Widget Factory and launch it. Or else, just type gtk4-widget-factory in your terminal.
4. Move your mouse over the window minimize and maximize buttons, and look at those, and also the close button.
5. See? Do you get these bad, dark square backgrounds?

Hardware and system info
Are you using LinuxMint 21, installed and up-to-date? On real hardware?
Please show us all the details by typing this in your terminal:

It seems this is only "my problem", but I am not so sure about this... Of course, I will probably, eventually, do a real LM 21 install, but this will take some time...

Okay. That was just my problem.

I guess that problem was caused by my virtual machine. I did a boot on a live LM 21 USB stick, and did apt install gtk-4-examples from there. I couldn't find any problem on real hardware. The window control buttons are okay, and the dark mode is also okay.
