Created attachment 170946 [details] video of flashing sidebar when moving mouse over it UI controls in sidebar are always flashing. Steps to reproduce: Open a Writer document. Open the sidebar, e.g. Properties or Styles deck. Observed: UI controls in the sidebar (e.g. icons, list of styles) are flashing when doing any action in LibreOffice - moving mouse cursor or typing. Firstly noticed in 7.0 series, persists in the current master. I tried to change some settings (hardware acceleration, Skia) with no effect. clean user profile, OS: Ubuntu 20.10 with Xfce desktop environment Tested in the latest master: Version: 7.2.0.0.alpha0+ / LibreOffice Community Build ID: 036053b969bf95a4cb9b16601f2651ca227dd429 CPU threads: 4; OS: Linux 5.8; UI render: default; VCL: gtk3 Locale: cs-CZ (cs_CZ.UTF-8); UI: en-US TinderBox: Linux-rpm_deb-x86_64@86-TDF, Branch:master, Time: 2021-04-03_01:38:00 Calc: threaded

Stanislav, can you retest your problem in 7.2.0.1 version? You can download it there https://www.libreoffice.org/donate/dl/deb-x86_64/7.2.0/cz/LibreOffice_7.2.0.1_Linux_x86-64_deb.tar.gz
Yes, still experienced in both 7.2.0.2 and the current master.

Do you still see this? Do you see this using other sessions besides Xfce?
Now, with 7.2.6.2 as part of the system and dev 7.4 alpha 0, most of the flickering is gone. It is still there when e.g. resizing the sidebar or using its scrollbar, but it does not happen when working on a document. I would consider this behaviour as acceptable and would agree with closing this.

Ok. It's not flickering for me even in those cases.
