Since quiet some time the right panel (permanent issue) and the font selection et al. (on hover) are flickering. I tried some of the older suggestions here in the forum to no avail f. e. switching OpenCL on and off does not make a difference.

Any hint appreciated.

I had this problem for years, regardless of LO and Linux desktop versions (currently I'm running Libreoffice 7.4 on Xubuntu 20.04). Very very irritating. Much of the toolbar would flicker on a fairly regular basis. None of the solutions out there worked for me. But, I finally solved it just now, thanks to this post:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=517671#c50

Turns out I had:

GTK_IM_MODULE=xim

set as an environment variable (use printenv to print out all your env variables). Looks like this was because I had an old file .xinputrc in my home directory, whose contents were run_im xim, which I think was manually setting the system input method to the old xim instead of the now default ibus. This file may have been inherited from an installation going all the way back to Ubuntu 10.10.

Deleting the file and rebooting solved it for me. No more flickering in Libreoffice! Amazing! Hope this helps.

Txs! Hmmm my `.xinputrc` tells me it's from 2018. Will try and report back here. -mgw

Looks like it's gone after restart. Also confirm that `.xinputrc` remains absent. Perfect! Txs a ton -mgw

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
