Richard Stallman <address@hidden> writes:* running the same build on the same debian sid machine under KDEwhen you run it under KDE, is that the GTK build of Emacs?It's the same build in all cases. The same binary files. I make a ".deb" package from the results of the build and install that same package on both machines, and run that same package under the various desktop environments. So in all cases it's using GTK.Unfortunately, the comparison between the two machines is not very conclusive because so many things could be different between them.I don't know if you saw the silly patch for the problem which I posted earlier today, but adding a static integer variable and incrementing it before incrementing interrupt_input_blocked in the #define for BLOCK_INPUT fixes the bug! I arrived at that fix through a process of trial and error, not through any understand at all of what's going on.
It is probably very timing related. A small change changes the timing. Can you try the attachet patch?
