--- Comment #93 from Sergio <sergio.callegari@gmail.com> ---
Unfortunately running things under strace just to get rid of some timing race
is a bit expensive in terms of wasted resources. 

From the strace manual:
A traced process runs slowly.

This is because strace operates in a slightly violent manner: pausing the
target process for each syscall so that the debugger can read state. This
happens twice: when the syscall begins, and when it ends.

Incidentally, this is possibly the reason why strace is effective in working
around the bug as it changes timings in rather strong way. 

So, it may be better to rely on nouveau (if possible) or on some other terminal
emulator like the one from LxQt (if it is not possible to use the nouveau
drivers) for the time being. Fortunately, the KDE Konsole seems to be the
single application affected by this (timing?) issue, which makes a replacement
possible (even if obviously undesirable).
