My current LO Version is 6.3.5.2.
For test purposes I deinstalled current LO and reinstalled 6.2.5 : the reported bug ist not present at this older version 6.2.5.
I also tested 6.4.1: the same bug appears.
Thanks for replying and the very good Draw, I love it.

I noticed OpenGL in your last comment, could you give a try at https://wiki.documentfoundation.org/QA/FirstSteps#Graphics-related_issues_.28OpenGL.29 ?

Hi, disabling OpenGL helped, the problem seems to be eliminated !

Activating OpenGL again, the bug is present again.

Thanks a lot for you help!

Question: 
Are there disadvanteges if OpenGL is disabled (e.g. a loss of functionality ?
Is the proper use of Metafile-Objects (stemming from converted Draw-Objects) still possible without OpenGL ?

Reason for my Question: 
one reason for using 6.3.5.2 instead of using  the former 6.2.5 is that there were problems with those metafile-objects.

Thanks a lot !
Olaf

I'm not an expert but I think OpenGL is just to accelerate LO by using graphic card so you won't lose any feature.

I submitted a patch to blacklist OpenGL for this specific device, see https://gerrit.libreoffice.org/c/core/+/91321

Julien Nabet committed a patch related to this issue.
It has been pushed to "master":

https://git.libreoffice.org/core/commit/d4c9e2130f6f065b4a97fc98cf1029593e725e65

tdf#131221: blacklist Intel on Win10 deviceid 0x5917

It will be available in 7.0.0.

The patch should be included in the daily builds available at
https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:
https://wiki.documentfoundation.org/Testing_Daily_Builds

Affected users are encouraged to test the fix and report feedback.

I don't think it worths it to backport the patch on 6.4 branch since we just need to disable openGL.

I disagree, users might not know how to do it. let's backport it.

Did you check that this is indeed a problem with this specific driver, and not a global problem affecting the OpenGL code path (in which case blacklisting this specific driver makes no sense)? There are more reports of this in Bug 126388 - Do they all use the same driver?

I didn't check this. I don't have any knowledge about OpenGL, I just know that there are lot of bugs related to it (because of LO or buggy drivers).
Feel free to revert the patch and investigate OpenGL if you want.
