Tabs missing until resize window

I have a Windows XP, Spark 2.5.4 user that is having problems with Tabs. When she opens a chat window, the tabs do not show up. Exiting and re-starting Spark did not help. What she did find is resizing the Chat window makes the tabs show up again. But if she then closes and opens the chat window, the tabs are gone again.

Has anyone else seen this?

Is there any way to fix this (having to resize the chat window every time will get old after a while)?

Hi,

I guess that this is a problem with the graphics driver. Spark had some problems with Direct3D, hopefully it is possible to update the driver of the graphic card. Of course it’s a little bit lame to blame another component but as the other Spark users do not have this problem it could be the reason.
