Xrdp high CPU usage

I have a ubuntu remote server to which I use RDP to connect from my local windows machine. I have installed Xrdp and the connection seems to work, but Xrdp process seems to have very high cpu usage (~50% while idle, and up to 100% when performing actions on the remote machine using the GUI)

Is this normal behavior? If not, how could I remedy this?

My first guess if that Xrdp is running using software rendering. But I am not sure how to enable hardware acceleration. Is it even possible on my setup?

Physical setup: Dell R740, S/N 3LQVGY2 CPU: Xeon Silver 4110 2 szt. RAM: 16GB 2666MHz RDIMM 2 szt. RAID H730P

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.
