Service Pack 2 causing display problems

[novak]

Having installed service pack 2 on our metaframe servers... all seemed to be fine for a while but then users started to experience display problems such as text disappearing, drop down menus flashing, columns disappearing, etc... moving the mouse sometimes brought the screen back to normal but only temporarily. It is definately a display setting somewhere.....I'm sure....
This was occuring on a 16 bit application we use but I removed service pack 2 before testing on other apps.

Can anyone help please ???

I have seen various display oddities following the installation of SP2/FR1, the most common being icons appearing upside-down.

The only fix I have found to date is to make sure that all users are running at 256 colours, and not using the high-colour options.

To my mind, however, this is unsatisfactory, and I am chasing this with Citrix.

CitrixEngineer,

I tried setting the display colors to 256 and it didn't seem to make a difference. Do you have any other suggestions?
Thanks,
Cale

Reducing the colours to 256 made no difference...in fact some of our published apps only have 16 colours and still managed to cause the display oddities......

novak, it's not so much the colour depth you're supplying the published apps at, more the colour depth the client is set to.

The issue is almost certainly with the client, from what I understand.

The only other fix I've heard of (as I put in your other post, Cale) is to change the graphics card in the client machine. This fix, as I understand it, deals specifically with the upside-down icon issue.

Another thing you could try, since I notice you say "moving the mouse sometimes brought the screen back to normal but only temporarily", is to set the minimum bitmap size in the cache settings to a larger amount.

I have seen graphics behave oddly when the bitmap size is set to the smallest possible, because at this size, even mouse cursor movements get cached.

Other things to look into are

Do these issues occur for all users?

If so, is this for all or only some apps?

What, exactly, are the apps - are any DOS-based?

Which clients are you using?

I have worked on the assumption that you are using the 6.0 Win32 client (the latest from Citrix's website).

This issue is certainly quite widespread, and I will post back when I have more information.

I hope this information is useful.
