Forms partially not visible until mouse hover

Postby developers10 » Mon Apr 10, 2017 1:37 pm

Several customers report the problem that the screens aren't always rendered.
They have to hover over it with their mouse-pointer to get it rendered completely.
I already tried setting this in the admin settings but to no avail :

complete setting :
Code: Select all
_JAVA_OPTIONS='-Dsun.java2d.opengl=true,-Dsun.java2d.d3d=false,-Dsun.java2d.noddraw=true'


This is what they see instead of the full grid:

Recent pc's running W7 and W10 64-bit.
Anyone any idea on how to solve this?
Thx

Do you see any exceptions in the java console when that happens?

You can go to the Java control panel, tab "Advanced", "Java console" and mark "Show console". Then restart the client. A small (ugly) console window appears next to your application window and there you should see exceptions when they occur.

Not yet been able to check. This is not so simple to ask an enduser.
We'll try to get a consultant to reproduce this when on premise with the customer.

Is this smart-client?

Make sure you have the java console open on that client.
Leave the smart-client on that PC unattended for like an hour, and see if it happens.

We have also a few PC's which have this...
and you will see a nullpointer exception in the java console.

This is the error you will see: https://support.servoy.com/browse/SVY-10621

Thanks, I'll give that a try. But as far as I understand there is no solution yet for the person experiencing this problem in the link you provided?
We still use 7.4.8 at the moment by the way.

Hi

I think your issue is the same as this case. We had experienced the same effect when hovering the mouse over table views.

https://forum.servoy.com/viewtopic.php?f=6&t=21430

Your issue was the same effect we had and was resolved with the fixes as per the case. We have seen this multiple times since and was always reproducible (missing table columns/rows).

Basically, an upgrade (by user) of the AMD graphics driver installs a couple of programs (without the user knowing) causing the issue. Removing the programs fixed the issue (outlined in the case).

Hope this helps.
