The easiest way to see the problem is to do on a VT: $ weston-launch -- --help I would expect that to print Weston's help text, but it seems to print one line of garbage in the middle of my bash prompt. If I redirect stdout and stderr to a file, the file gets the correct printouts. I assume weston-launch is changing the console modes such that printing gets scrambled. I wonder if this is even fixable. It also prevents seeing weston backtraces on the console if weston crashes. Tested with the latest git revision.
Thanks to mceier, a new hint: $ clear; weston-launch -- --help works just fine fine, although it does not print enough lines to trigger scrolling. So it's something about scrolling broken?
Once we switch the VT to KD_GRAPHICS mode, the console stops working. X has the same problem if you start it with the -keeptty option. To keep logs pipe stderr to a file.
