If this is the wrong part of the stack-universe, please feel free to move this, this was my best guess as to where to ask.
I have a website, in citrix, on chrome, only when the chrome window is maximized, when selecting from a drop down list, the dirty screen refresh (system code that only refreshes the part of the screen has changed) messes up, and part of the drop down farther away from the original control gets left not redrawn.
I've tried it both with new and very old code, and if you de-maximize the chrome window it stops and everything is ok.
This indicates strongly to me, that it's probably either a setting in chrome, or much more likely a setting in Citrix interacting with chrome.
I'm hoping someone here can point me towards things in Citrix to investigate.
