Transmission GTK errors - syslog contains millions (literally) of errors daily and in app labels and layouts regularly become confused

I have transmission running on this computer loading at startup. I am running Ubuntu 22.04 LTS and have installed latest updates.

When I access the app to inspect torrent properties the labels on the windows and tabs become confused often showing text from elsewhere instead of the correct information

Example of incorrect labels

When I examine syslog (for other reasons) I find it is full of GTK errors from transmission. There are literally millions of the daily! I include a sample

I am assuming that these are different manifestations of the same problem.

Also Transmission regularly crashes but given all these errors this is hardly surprising!

Anyone got any suggestions as to what is wrong, how to fix etc

Any help welcomed

Thanks

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.
