problems with application title bar

[IvanDeFelice76]

the extension causes problems with the application title bar, so far detected in "Nautilus and Gnome-tweak-tool".

the title bar often blinks and becomes transparent and the letters are sometimes illegible

Thanks for the issue, are you using X11 or wayland?
That's a weird bug for sure...

Grazie per il problema, stai usando X11 o Wayland?
Questo è sicuramente un bug strano ...

I use Wayland, but it seems to do it on both also because it's the first thing I thought too...unfortunately screen doesn't come out the way I see it, but the bar becomes transparent and characters almost seem to mix!!!

I will try to repeat it on my own computer! But I'm not sure to be able to do it :/

Proverò a ripeterlo sul mio computer! Ma non sono sicuro di poterlo fare: /

Hi,

Same issue with gnome-shell 3.38.4 under X11.

Video card : GeForce GTX 1660 Ti with using proprietary drivers

[aunetx]

Could you try to screen-record it? I don't exactly understand what happens... But it looks a lot like an issue I had under virtualbox, when testing the extension.

Does it happen under gnome 40 too (if you can test)?
For me on virtualbox, it looked to be tied to some drivers issues, as disabling 3d acceleration removed the bug (I think?)

Hi,

I have make a screen record with some apps to view the bug.
I can't test actually with G40 but it will not be long. I will keep you informed as soon as I have this version.
