Does this happen all the time, or only occasionally?

I ask this question because I have noticed a similar issue (a terminal
flickering phenomenon that I first noticed after upgrading to
stretch), but it only occurs after I've resized a terminal (xterm)
while running a certain application (lynx) in the foreground. (I don't
use w3m.)

My workaround is to put the offending application (lynx in my case) in
the background before resizing its terminal, and not to bring it back
into the foreground without first restoring the terminal to its
original size.

Or, when using the affected application within a terminal multiplexer
like GNU screen, there are other workarounds available. (Namely, to
keep windows running applications susceptible to flickering-on-resize
hidden, until the terminal is restored to its original size.)

Basically, if OP's problem is the same problem I have noticed, the key
to avoiding it seems to be this: Never make the affected application
adapt itself to a resized terminal.
