Reporter:	bennie vaughan	Email Updates:
Status:	Not a Bug	Impact on me:	None
Category:	MySQL Workbench: Modeling	Severity:	S2 (Serious)
Version:	5.2.26 CE rev 6432, 5.2.27, 5.2.28, 5.2.29	OS:	Windows (Vista Business Service Pack 1 32 bit)
Assigned to:		CPU Architecture:	Any
Tags:	Canvas.h, driver, exception, workbench

Description:
Workbench generates a exception any time a design block is connected to another block. After a few exception blocks acknowledgements. All is ok until cursor is over a connect line or block that is connected.

How to repeat:
create 2 tables then connect with 1:1 or any others connection type. After acknoledgement of exceptions move cursor over connecting line or table block; will get error.

Thank you for the bug report. I couldn't repeat or I didn't understand how to repeat, it is possible to attach a screen-shot which shows how to repeat?. Thanks in advance.

here is the error:

Unkown Exception caught in c:\documents and
settings\mysqldev\build\mysql-workbench-gpl-5.2.26\backend\window\wbpublic.wr\Canvas.h at line 152

unable to get a screen shot at this time...

Please note that with the mwb I've provided, the bug is present with the 5.2.26 and 5.2.24rc but work fine with 5.2.21rc (all the versions a still have).

Please, check if this ever happens with a newer version, 5.2.27.

Hi!

I'm back.. :)

Sorry for the delay but unfortunately, yes, the bug is still present with v.27..

Yes, it's still present (canvas.h at line 171)..

Bug #57201 was marked as a duplicate of this one.

All reporters, please, check if starting Workbench from command line with -swrendering option prevents this problem.

Bug #57404 was marked as a duplicate of this one.

Hi!

As of version 5.2.29CE, the bug is still present; BUT, with the parameter "-swrendering", all works fine in GDI mode on the faulty workstation.

(the NOD tricked my OpenGL driver? ;) )

The addition of "-swrendering" at the command line corrected the problem.

If anyone has access to other machines with ATI cards, could you please test if the same happens in these?

Also, please make sure you have the latest drivers for video.

Also, what drivers are you using? The one that comes with Windows or the ones provided by ATI?

Hi!

I wasn't using the Windows's default drivers but the ones provided by Dell.

I've updated the drivers, downloading them directly at ATI and all works fine now.

so i'll close this as a driver issue. thanks for the update
