Hi
Latest intel driver breaks 1680x1050 mode on TMDS-1 output only (works
fine when using VGA output). Monitor gets 1680x1053 instead and breaks
the picture by scaling in y direction. I bisected the driver to figure
out which commit changed the behaviour:

Fix load detection to use border region instead of blanking.
Make sure there is some border area to use by changing how the pipe is
configured, then pick a scanline in the middle of the border for load
detection. This lets the load detect code use an active pipe instead of
requiring an idle one.
I've added Bug #11663 for this issue, where I also attached
logfile(s).
Best regard,
Stefan
