Artifacts in display on Kubuntu 20.10

Since a few days, I'm seeing strange artifacts in Kubuntu 20.10 on both of my monitors. See https://imgur.com/a/pd2ZgHY for two examples. Because I'm seeing it on both of my monitors and only while using Ubuntu (not Windows), I guess it is a software issue. Some info:

• Operating System: Kubuntu 20.10
• KDE Plasma Version: 5.19.5 KDE
• Processors: 4 × Intel® Core™ i5-3470S CPU @ 2.90GHz
• Memory: 15,5 GiB of RAM Graphics Processor:
• Mesa DRI Intel® HD Graphics 2500

Let me know if more info is required.
