Description: Ellipses are rendered with strange wiggles. Steps to Reproduce: 1. Draw an ellipse in LibreOffice Impress. 2. Copy the slide. Actual Results: The copied slide shows the attached rendering artifacts. Expected Results: Slide should look like the original. Reproducible: Sometimes User Profile Reset: No Additional Info: This only occurs sometimes. Switching between slides also triggers the odd rendering sometimes. Switching to presentation mode shows the ellipses correctly (at least every time I tried). I am on an up-to-date Ubuntu linux with X. I disabled "OpenCL", "Hardware acceleration" and "anti-aliasing" in Options -> LibreOffice. I also have the issue with "Hardware acceleration" turned on.

I could not reproduce on Ubuntu 20.04 with: Version: 7.3.7.2 / LibreOffice Community Build ID: e114eadc50a9ff8d8c8a0567d6da8f454beeb84f CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3 Locale: en-AU (en_AU.UTF-8); UI: en-US Calc: threaded Can you please: - update to a currently supported version (7.5 ideally) - test again and see if the issue remains. If it does: - share an example document so we can test in the same conditions - paste here the info copied from Help > About LibreOffice Thank you!

Created attachment 188188 [details] Example impress presentation 1. I started a new document 2. I added two ellipses to the first slide. 3. I copied the first slide (CTRL-C CTRL-V). The new slide looked ok. 4. I clicked again on the first slide, and duplicated it again (CTRL-C CTRL-V). The new slide (slide 2) looked wiggly. Closing the file and reopening it, the first slide looks okay. The second and third look wiggly. Closing the file and reopening it again gives the same.

(In reply to Johannes Buchner from comment #5) Thanks you for the file and steps. Unfortunately, still no repro for me with same version as in comment 3. (In reply to Johannes Buchner from comment #6) > Unfortunately, I do not think I can test pre-release versions soon on this > computer. Version 7.5 is not pre-release, it is the only stable version that we currently support and that will see fixes. You can install it alongside previous version and later delete it if you want, using the debs: https://www.libreoffice.org/download/download-libreoffice/ Please also test with Help > Restart in Safe Mode. Cheers
Thank you Stéphane for the pointers. I was able to reproduce the behaviour with 7.5.
I used the Safe Mode menu dialog to "configure" and disable user extensions and hardware acceleration. Then I could no longer reproduce. I then closed and opened impress normally (with 7.3), and now the bug no longer appears. I cannot reproduce it anymore. I guess this bug can be closed as resolved?
Resolving as "works for me", looks like it was somehow linked to your user profile (if you are still using the same graphics settings as before). Let us know if the issue pops up again (and share your Tools > Options > LibreOffice > View settings with us). Thanks!
