Bug#829259: x11-xserver-utils: xrandr causes short screen pause
Package: x11-xserver-utils
Version: 7.7+7
Severity: minor
Dear Maintainer,
While observing HTML5 video playback in the Chromium web browser (tested
against version 34 and 51), I noticed the xrandr command causes playback
to hitch for a few frames (verified using the fps counter overlay in
Chromium). I am running the command:
xrandr -d :0 -q
The particular devices we're seeing this on are an Intel NUC6i5SYH and a
Dell Optiplex 3020. lspci shows:
NUC -
00:02.0 VGA compatible controller: Intel Corporation Sky Lake Integrated
Graphics (rev 07)
Optiplex -
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th
Gen Core Processor Integrated Graphics Controller (rev 06)
The reasons we're bringing this to you is because I'm aware there have
been issues with the Skylake chipset and we do not notice the issue on
older hardware, such as an HP MP9 on which lspci shows:
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th
Gen Core Processor Integrated Graphics Controller (rev 06)
What's odd is it only happens if a minute or so passes between calls. If
I make consecutive calls frequently, it doesn't cause the pause.
