Mouse clicked down/click and drag bug in impress

Hi, I’m running impress on Ubuntu 19.10. There seems to be a strange bug where the mouse is held down, for example when i click on a slide, it opens fine, but then when i hover over a different slide, it highlights all the slides between the slide I just clicked and the slide I’m pointing to. This leads me to believe there’s a strange bug where my left mouse is perceived by impress as down even when it isn’t. Any idea how to fix this? I don’t get this bug with calc or writer.

Rebooting appears to have fixed the issue. Will update if it returns.

Thanks for posting the solution, you saved me a lot of time.

I have this problem too. On Ubuntu 20.04 and LibreOffice

After reboot the problem is gone, but a restart of LibreOffice Impress does not change anything.

Problem description: MouseOver marks a slide (in the overview), and moving the cursor up and down marks multiple slides. Moving the mouse to the work-area (on the right), makes Impress attempt to drag slide.
Only way to change/select a single slide is by double-clicking.
This is very anoying and hampering in ones work.
