Terminal flashes black when focus is changed

I have a light background on xfce4-terminal 0.6.3 (I'm on Arch Linux) and when it's in non-minimized state it's window background constantly flashes (all window's area is filled with the black color for a fraction of second) when the terminal window is minimized or receives focus or loses focus or when the workspace is switched. Other terminals (e.g. XTerm) doesn't have such behaviour. I tried to add to ~/.Xresources the following:

xfce4-terminal*background: rgb:ff/ff/ff
xfce4-terminal*pointerColorBackground: white

but this hasn't changed anything.

How to get rid of this background's color changing?

Re: Terminal flashes black when focus is changed

Hello and welcome.

Lets confirm a few things:
1. What kind of video card do you have and which video driver are you using?
2. Do you have display compositing enabled?
3. And can you post back your terminal settings (found in ~/.config/xfce4/terminal/terminalrc)?

Re: Terminal flashes black when focus is changed

ToZ,

I have a SiS videocard:

VGA compatible controller [0300]: Silicon Integrated Systems [SiS] 661/741/760 PCI/AGP or 662/761Gx PCIE VGA Display Adapter [1039:6330] (rev 04) (prog-if 00 [VGA controller])

Video driver is xf86-video-vesa.

Is there any reason that you are not using the SIS driver (xf86-video-sis)?

Display compositing is disabled.

Can you try with combinations of display composting enabled and transparent background to see if the flicker is eliminated?

Re: Terminal flashes black when focus is changed

ToZ,

When I was installing the video driver a year ago, the xf86-video-sis didn't work with my video card. There was information that 'xf86-video-sis' is outdated and recommendation to use vesa driver.

With compositing enabled and transparent background the terminal background doesn't flicker. ( Compositing makes UI responsiveness somewhat slower on my hardware, but if there is no other way, I may leave it turned on.)

Re: Terminal flashes black when focus is changed

It must have something to do with the vesa driver and the way xfce4-terminal is coded. I'm afraid I don't know the specifics. I see you've created a bug report for this - maybe one of the developers will comment on the report if you add this extra information to it.
