Hello, insert mode in uzbl on debian wheezy (mipsel architecture) is terribly slow and if one types at normal speeds, letters are missed or overwritten. Please let me know if you need more info or if there are actions to be taken to speed this up.

I've seen this before on sites that have fancy textareas (syntax highlighting, etc.). Are you experiencing this on sites with plain textareas as well?

Typing is slow in plain text areas. This might be specific to the mipsel architecture or some configuration I have on this machine because this does not occur on an i386 machine that I have also running debian wheezy.

Hmm, ok. If this is the same as the bug I'm experiencing, I've had success commenting out this line in uzbl-core.c:

"signal::selection-changed", (GCallback)selection_changed_cb, NULL,

Can you compile from source? If so, please try commenting out that line.

thanks for the tip! I'll give that a try.

Additional Info:

I am encountering the same issue on my i686 machine running Arch Linux (this is a VMware image). For me, this issue happens frequently while the CPU usage is high , 50% to 90% (uzbl-core and python2 being the top two CPU consumers). But it also happens, although intermittently, while CPU usage is relatively low.

A simple Google search or typing in a plain text area, its quiet annoying to see characters getting overwritten.

VMware Workstation 7.0.0.
VMware Host System => Windows XP SP3.

I'll see if I can compile from source and comment out the line cited above. Thanks for the info.

I've pushed the workaround I suggested to the master branch (it was also a fix for bug #296), if that helps anyone test it out.
