Are you running OSX? If yes, you may try to set
the buffered_drawing option in .dillo/dillorc to 0 or 2.
There are still open issues with dillo 2.0 on OSX. The
main development platform is X11 on Linux / *BSD.
Please help improving the situation on OSX by reporting
open issues on dillo-dev@dillo.org.

Nope, not on OSX. I'm running Slackware-current, xorg-server-1.4.2, nvidia-177.78.

buffered_drawing=0|2 Neither make a difference here.

Hm, on Linux it should work just fine.
Did You compile fltk2 yourself or is there a pre-built package
for Slackware?
In case you compiled it yourself, you might check whether the
test programs in the fltk2 tarball work ok on your system.
Also please verify that You don't have two different versions of
fltk2 installed (e.g. on in /usr and one in /usr/local).
Could you please report back on this issue on the Dillo mailling
list (dillo-dev@dillo.org) so that other developers can help?

I checked several things...
I had dillo 0.8.6 installed (claws-mail uses it as a plugin)
I also had fltk-1.1.7 installed.
I removed them both.
I recompiled fltk2-2.0.x_r6403 myself, then dillo2.
Still the same weird window-turns-invisible when I move the mouse over the toolbar icons.

I'll take this over to the Dillo list.

Just for the record, it turned out that the --enable-cairo switch
of the fltk2 configure script caused these issues.
So please verify that fltk2 has not been compiled with this option.
You can check this be running

fltk2-config --ldflags | grep cairo

there should be no output.

I had the --enable-cairo configure option set. Thanks for the heads up.
Will re-build without it.

Are other programs exhibiting such problems, and are you running compiz? There seems to be a compiz-nvidia-xdamage interaction that causes similar problems (that I too have run into). The problem is discussed here. A workaround for compiz suggested here (disable --loose-bindings for compiz) fixed it for me.

If you're not using compiz, perhaps fltk or some other library used by dillo suffers the same problem. Do you use other fltk programs?

I get similar erratic behaviour, too (using a somewhat older version of fltk2). If I start dillo 2.0 from a terminal window, I get the following error message:

XOpenIM() failed

What system do You have (OS, distribution, 32bit/64bit, graphics card)?

Thanks for your help offer, but the window redrawing problem (when moving mouse pointer over dillo's toolbar) disappeared after I upgraded fltk from version 2.0.x-r6159 to 2.0.x-r6403. I still get the "XOpenIM() failed" message when I start dillo 2.0 from a terminal window.

My system is Linux, 32bit, and I'm using the proprietary nvidia driver.

Thanks to jh33's help, I have to say Dillo2 is working well for me.

Don't enable cairo support in the fltk2 library. It seems to not be ready for prime time. With a rebuilt fltk. Dillo2 is working great.

None of the issues I raised are still apparent.

Good Job Dillo Team!
