Some windows become whiter with mouse over and eventually white out.

Hi.

I'm just bought chromebook and starting to use xfce4 under crouton.
So maybe it isn't the right place to ask about but...

As I titled as "some windows become whiter with mouse over and eventually white out", it's like below.

Affected windows are guitarix, thunar, the Preference window of xfce4-terminal and so on.

I went xfce4-setting-manager -> Window Manager Tweaks -> Compositor and
set Opacity parameters as full Opaque.

Are there any place to change prameters?

Please give me some advice to address the problem.

Best regards,
Aki

Re: Some windows become whiter with mouse over and eventually white out.

Which version of Xfce are you running?

Which Appearance (GTK) theme is currently selected? Does changing the Appearance theme make a difference?

Does disabling the compositor help?

What video card do you have and which driver are you using?

Re: Some windows become whiter with mouse over and eventually white out.

Xfce version is 4.14 from ubuntu focal.
I use Greybird-dark Style.
I tried other themes with gtk-theme-switch, but no good.
Unchecking "Enable display compositing" also have no difference or worse.
The window of Window Manager Tweaks is getting whiter with unchecking.

Thanks.

Re: Some windows become whiter with mouse over and eventually white out.

What do the following commands return:

xfconf-query -c xsettings -p /Net/ThemeName
xfwm4 -V
ps -ef | grep xfwm4
ls /usr/share/themes/$(xfconf-query -c xsettings -p /Net/ThemeName)
lspci -vnk | grep -A12 VGA

What happens if you start guitarx like this:

GTK_RC_FILES=/usr/share/themes/Raleigh/gtk-2.0/gtkrc guitarx

You also mention thunar was a problem but its not in your screenshot. To confirm, is this also happening with thunar? If so, does this help?

thunar -q && GTK_THEME=Adwaita thunar

Then it must have something to do with your video card if screenshooter is capturing a rendered screen. Perhaps its best to reach out to the Crouton forums and see if the video card is set up properly.
