We have been deploying CEMR via Citrix for quite a while now, but recently we have started seeing visual bugs with the UI. This appears to only be happening with computers which have updated from Citrix Receiver to Citrix Workspace.
Application windows will appear with a black border on the right and bottom sides of the window and the content in the window will be slightly blurry. It's almost as if the windows isn't loading to the full size that is designated for it.
This seems to be confirmed when you try to interact with the window. If you try to click something in the affected window, especially a small item like the checkbox on the care alert in my picture, you must click to the bottom right of the box for the click to actually check off the box.
This is mostly seen when a window appears on top of the main application, but we have gotten a report of this happening to the main application. This does not happen every time a window loads, but happens consistently enough that it is seen a few times a day.
I have tried to check server logs but nothing appears. This also doesn't seem to be related to high or low traffic on that particular Citrix server.
We do deploy quite a few other apps through Citrix, but CEMR is the only application that has had this issue reported. Nothing in our environment has changed besides the devices having Workspace instead of Receiver.
Is anyone else seeing this issue? Any ideas or Citrix settings that could help with this? Virence case ended with "we haven't heard of this before".

I've not seen this before specifically, however, I have a suspicion that might warrant investigation by engineering. In the past, incidents of visual anomalies have increased multi-fold since 'GE' introduced the new form 'skin' to the EMR in both fat clients and more so in thin clients.
Encounter forms were the first place to demonstrate that these skins do not properly fit the controls they color/draw appropriately. There is a pattern of 'trailing and bottom edge truncation' that is well established.
That stated, my gut tells me that the modal pop-up is actually the size that the outline is showing but the skin is not fitting it properly - sort of a hidden shadow effect type of thing. Supporting that notion is the bottom edge spacing between the check box and 'frame' - there simply should be more room (equal to that above it).
I could be off, but I would ask Engineering to reopen the ticket and examine this as the culprit. You might be able to verify this by turning off the skinning (is that still an option? Not looked in a while).
Good Luck!

Hey Guys - I shared this post with my network administrator and he emailed me back this information - sharing here in case it helps you:
Tom had a couple users we gave new laptops experience the blurriness issue you shared from CHUG. We tried some changes to the settings below along with a display setting under 'advanced scaling' which may be specific to either certain builds of windows 10 and/ or certain video drivers on windows 10 systems. My win10 build 1709 system doesn't have 'advanced scaling' on the display settings page. The setting to change on the advanced scaling page is to 'have windows manage scaling so apps aren't blurry.'
I think Tom changed the windows setting, didn't see an effect, then changed citrix, also with no change, then relaunched the app and it worked. I've asked him to retest more carefully so we understand if only 1 or both are required and can push the right setting for all. Yes may work if the windows option isn't there, or there is a chance it needs both the windows option and the citrix option changed. It may also not be an issue if the windows option isn't available, as I don't have noticeable blurriness on my system with workspace.
(I can't include the screenshot but it's Advanced Preferences > Scale this session for high resolution? and they changed it to "No, use the native resolution" - HB)

One more update from our network administrator: the user that was having the problem had changed a display setting under scale and layout "Change the size of text, apps, and other items" to 150%. This was factoring into the resolution problem and also had some forms not displaying text correctly (it was getting cut off). We changed the scale back to 100%. We think the above information may apply, but we wonder if the problem doesn't present until font sizing is changed. FYI.

I tried this as well and it seems to be effecting users regardless of what I set the "High DPI" setting to in Citrix. We are experiencing this on Windows 7 and 10, with both high and low resolution monitors. I just checked and our scaling is set to 100% in our display settings on our Windows 10 devices.
It doesn't happen all the time, just maybe 5% or less of the time that a window is opened. So every time I think I might have fixed it, it pops back up later that day or the next day.
For now we have opted to downgrade users to Citrix Receiver 4.12. We will be upgrading our Centricity server and Citrix environment from Windows 2008 to 2012 soon as well as upgrading Centricity from 9.8.10 to 9.12.3. I am hoping that with these changes we might see this issue resolve itself, but for now we will remain on the stable Receiver 4.12.
If it still seems to have been fixed for you after a couple days, I'd definitely like to know. Maybe I missed something.
