If anyone else was ready to pull their hair out due to reported issues of slowness in Citrix around the same time all the CrowdStrike fun started, please know that certain machines (in our case Lenovo T14 Gen 4 and T16 Gen 2) pulled down driver updates from MS overnight Thurs/Fri for the Intel UHD Graphics adapter that introduced the issue described at https://community.citrix.com/forums/topic/248347-fix-for-horrible-performance-on-dell-7[…]d-750-graphics-slow-panning-slow-scrolling-screen-lag-etc/ Can confirm that it is resolved by setting UseD3DHybrid to 0x0 under HKLM\SOFTWARE\WOW6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\GfxRender We are using Workspace 2402 LTSR Talk about bad timing....

The UHD driver thing has been the bane of a lot of our end users existence for some time. But yes, seems the messaging 2 weeks ago for all of our users to upgrade CWA, which went a long with...if your CWA is too old uninstall/reinstall vs in place upgrade... also nuked the aformentioned regkey (expected due to the actions above...but still 💩 that we didn't take it into consideration)

@Jay Moock which driver version are you running? Is it an Intel Arc GPU? https://www.intel.com/content/www/us/en/support/articles/000097751/graphics.html

😛 Hi Rody, I'll have to check with our users who were impacted. We're all BYOD

The client graphics adapter is Intel UHD Graphics, and the affected version is 31.0.101.5590. The updates that impacted us are in the attached image (we have our clients pointed to MS for driver updates):

Timely thread - I just got a new Lenovo T14s with Intel GPU and was up to 2am last night logged into a client via Citrix to do some upgrades, cursing all the time as to why the Citrix session was so slow and TeamViewer was faster, couldn't figure it out. The most recent driver installed by the Lenovo update tool is 31.0.101.5388, I'll try a later version direct from Intel.

Can confirm that latest intel Iris/Arc graphics driver solved issues for us and we also rolled out the new LTSR VDA

Intel updated their KB article: https://www.intel.com/content/www/us/en/support/articles/000097751/graphics.html. The latest Arc driver, 31.0.101.5594 or newer, resolves these issues.
