Resolved Issues 11.08.440

Citrix

• Fixed: Situations where hardware decoder has not enough memory to handle certain video formats properly, are optimized / better handled now.
• Fixed: In rare situations (observed when using teams app sharing) intermixed video frames appear which come from different H.264 streams. These frames are now being separated from each other and will be decoded separately.

• Added a new registry key to suppress such secondary frames entirely, as they render mostly duplicated content of the primary frames.

  Parameter	In case of mixed up H264 streams: Don't display frames from secondary streams
  Registry	ica.hw-accelerated-h264-suppress-secondary-frames
  Type	bool
  Value	enabled (default) / disabled

• Fixed: Refresh/Redraw issues of Citrix session windows. Resuming from screensaver or uncovering a session window which was covered by another window works as expected now.
• Fixed: dynamic e911 feature.

• Added registry key ica.chrome-double-download to control flock feature at wfica_wrapper. Enable flock blocks double app starts (due to double downloads by Chromium browser).

  Parameter	Control download mechanic for Citrix applications for Chrome web access
  Registry	ica.chrome-double-download
  Range	[Enable Lock][Disable Lock]
  Value	enable / disable (default)

• Fixed: Web-based Citrix Cloud authentication pages.
• Changed: Default for ica.module.audioredirectionv4=true due to connection problems with some VDI versions.
• Fixed: H.264 streams with multiple reference frames (as produced by hardware encoders) are supported properly and do not lead to a potential crash any more.
• Fixed: In special situations, certain frames did not show up on the screen when VDPAU was configured.

AVD

• Improved: MS Teams video quality optimizations applied.
• Fixed broken appbar - which can be enabled with System > Registry > sessions.wvd%.options.cmd_ext = -a
• Changed the x264enc QP setting to do less aggressive video quantization to improve outgoing video quality in MS Teams.
• Fixed autostartsingle registry option.
• Fixed screenshare issue with direct MS Teams calls when a screenshare is already active.
• Fixed potential client crash when virtual backgrounds are enabled in MS Teams.
• Fixed stale video window content in MS Teams when video feeds are switched, but incoming video is not directly decodable.
• Adjusted the quantization range for the x264enc to allow a little more quantization being applied to outgoing MS Teams video streams.
• Fixed: Avoid large display delay of incoming MS Teams video streams by measuring NTP latency.

RDP/IGEL RDP Client 2

• Fixed RDP timezone redirection not working for some locations.
• Fixed fullscreen RDP session not starting with no monitor connected.

VMware Horizon

• Fixed: Horizon session starter cannot handle backslashes in password.

Chromium

• Added registry key to toggle prompt to accept downloads:

  Parameter	Enable IGEL Download Dialog
  Registry	chromiumglobal.app.enable_download_dialog
  Type	bool
  Value	enabled (default) / disabled

Network

• Fixed network configuration on HyperV.
• Added possibility to set an antenna bitmap to configure which antenna should be used (for iwlwifi devices)

• Added new registry key to configure the antenna bitmap

  Parameter	Tx antenna bitmap
  Registry	network.interfaces.wirelesslan.device0.antenna_bitmap_tx
  Type	string
  Value	empty Default

  Parameter	Rx antenna bitmap
  Registry	network.interfaces.wirelesslan.device0.antenna_bitmap_rx
  Type	string
  Value	empty Default

• Improved behaviour of WWAN devices on suspend/resume
• Fixed setting credentials for system-wide proxy.

Cisco Webex

• Renamed libstdc++.so.6, Webex Meetings client expects the highest version of libstdc++.so.6.

Base System

• Added new registry key to set acpi= kernel cmdline options (some devices needs acpi=off).

  Parameter	Set ACPI kernel parameters.
  Registry	system.kernel.bootparams.acpi
  Range	[No setting][Force][On][Off][Noirq][Strict][Rsdt][Copy_dsdt]
  Value	No setting

• Added new registry key to set reboot kernel cmdline which can be used if reboot or shutdown issues are present

  Parameter	Set reboot kernel parameters.
  Registry	system.kernel.bootparams.reboot
  Range	[Default][Bios][Triple][Kbd][Acpi][Efi][Pci]
  Value	Default

• Fixed issue with ELO AccuTouch not picking up selection.

• Changed the handle_brightness_keys default to enabled, as this setting is needed for most of the current laptops anyways.

  Parameter	Handle Brightness Keys
  Registry	x.xserver%.handle_brightness_keys
  Type	bool
  Value	enabled (default) / disabled

• Fixed instability in handling of certain webcam devices, e.g. Meeting Owl 3.
• Added licensing information for Lenovo's FCC unlock tool.
• Use s2idle on HP mt440 G3 as it works better

• Changed registry key to be able to use mem sleep mode depending on hardware

  Parameter	Set suspend mem sleep mode.
  Registry	system.suspend.sleep_mode
  Range	[Default][Suspend to RAM][Suspend to idle]
  Value	Default

H264

• Fixed: H.264 streams with multiple reference frames (as produced by hardware encoders) are supported properly and do not lead to a potential crash anymore.
• Fixed: In special situations, certain frames did not show up on the screen when VDPAU was configured.

X11 System

• Changed default setting for DisplayLink Quirk which solves an issue with long startup times

• Registry key parameter now defaults to true:

  Parameter	Quirk to fix issues with Xorg start take ages with DisplayLink connected.
  Registry	x.xserver%.quirks.displaylink_crash_workaround
  Type	bool
  Value	enabled (default) / disabled

Audio

• Fixed: Sound preferences not getting saved over reboot.

Remote Management

• Added: Create log for support information if rmagent has been requested to release the device from UMS.
• Retrieve the device's unit ID in more robust way.
• The log file is only accessible to root
