@pehar: This seems to be fixed. Please have a look yourself, this is functionality that I do not use myself so I might overlook something.
dt 3.1.0+1009 PR 494b65a
Just updated (master dt 3.1.0+1016). I can still force the jitter, but the behaviour is slightly different as before. Can be reproduced this way :
- preferences → GUI options → show scrollbars for center view should be set to lighttable + darkroom
- adjust the height of the filmstrip and/or the side panels to make the image fit nicely
- press Alt+2, no jitter (in contrast to before)
- widen sidebar (left or right) slowly, jitter starts when scrollbar (horizontal or vertical) is needed
If one moves the mouse faster when widening the sidebar, the jitter can not be forced anymore. The behaviour varies slightly depending on the hardware. On a new (fast) system (CPU with 6 cores, hyperthreading + Nvidia 2060 GPU) it is easier to force the jitter.
The actual behaviour is a considerable improvement, but there are still (rare) cases where jitter can occur. In my opinion the actual status is OK.
Yes, I see that behaviour as well. As you mentioned yourself: rare cases.
Am I correct in assuming this issue can now be closed?
Yes, I think so !
