Performance for le clear in Uniface 10.4

We are trying to migrate from U9.7 to U10.4 since several weeks.
The last problem we have is a very bad performance of the clear proc in our frms.
We use the function $paintedfieldproperties to construct our grid with a "Sheet" aspect like the screenshot below.
After a retrieve for example, when the screen is full of data , now, when we do the classic "clear" process  to empty the screen as usual,
the lines goes empty but very slowly, line by line...
It is not at all the case with Uniface 9.7, actually in production mode.
This gives a very bad user experience and may jeopardize our migration to U10.
Is there a way to improve this clear process ?
Thank you very much for your help
PS: we are testing U 10.4.01.003

Ciao Daniel,

my gotfeel reaction is: what could be happening here? clear instruction is not an issue for me since U5!

Uniface screen driver is always painting on screen from bottom to top; in some cases I have seen the runtime clearing row by row but always fast enough to not be considered an issue.

Usually my use case for $paintedfieldproperties is to put a button on top of a label or to move a field in a specific position. I never used it to paint a whole (and probably complex!) grid.

The picture you've posted does NOT seems to require a lot of "... function $paintedfieldproperties to construct our grid with a "Sheet" aspect like the screenshot below ..." because a Uniface form with occurrences repetition is already a "grid with a "Sheet" aspect".

My thoughts leads to my questions:
- what use for $paintedfieldproperties are you coding?
- in your <CLEAR> action the performance issue is verified for a simple clear instruction or do you have a more complex coding for that?

Regards,
Gianni

Ciao Daniel,

IMHO because of your use case Uniface runtime if forced to clear fields one by one and considering the grid is including many fields it is requiring time.

If effectively U9 does not shown same (bad) behaviour, being in your shoes I would open a case with support about performance regression.

Have a nice sunday!

Could you try if disabling the PaintCache INI-setting resolves the performance issue?

[upi]
PaintCache= False

By default the mentioned setting is enabled ("True").

I hope this helps.
