Qt 6.3: stylesheets with QLineEdit makes the placeholder color same as text

Hi,

That looks like a possible bug.

Can you provide a minimal compilable example that shows this behaviour ?

@SGaist Hello, here is a minimal example, made with QtCreator: Google Drive link.

Hello again. Sorry for the double post, but have you had time to check my example project yet?

Not yet, will do ASAP

I can confirm the behaviour change between Qt 5 and Qt 6 on Linux.

You should check the bug report system to see if it's something known. If not, please consider opening a new report providing your example.

@SGaist Hello,
Thanks for the confirmation!

I just checked on the bug report system, and it seems that is is a known bug since the early development of Qt 6 :/
There are already 4 or 5 tickets talking about this issue or related things (QSS / QPalette).
All the tickets are in low priority, I'm a little bit sad about that, but I guess I will just have to wait more to use Qt 6, and stick with 5.15.2 for a while ^^

Can you link what you found ?
Is there any of these that related to your issue ?

For those of you who would find this post and are looking for a solution, I used this workaround, on Qt 6.3.1 :
