xorg.conf
This is caused by gtk calling XRRGetScreenResources() on application start, which probes all outputs. The effect you see is caused by load detect. While it may be possible to avoid load detect, it is not by definition our bug. I'm leaving this to Stuart Bennett, who knows more about the code. I've just pushed a commit that should reduce the load detect side effects "randr12: don't use in use (by another vga output) crtc for load detect (avoids flicker)". Obviously this still leaves the rather stupid behaviour of gtk, but you'll have to get someone else to fix that. So, please try using a updated git checkout and close the bug if the flicker is gone. |
