Hello Thomas,
Yesterday, I mentioned that disabling the timer resolved the issue, meaning
the UI dragging problem disappeared. However, the layout functionality was
affected. I suspect the problem lies in the run_layout function.
I also tried reducing the timer delay, but the issue still persists.
Today, I further traced the code and focused on the restoreFromLayout
function in qt_layout.py. When I removed vr3 as shown below, the UI behaved
normally:
if *0*: # has_vr3
if (vr3 := self.find_widget('viewrendered3_pane')) is None:
import leo.plugins.viewrendered3 as vr3_mod
vr3 = vr3_mod.getVr3({'c': self.c})
vr3.setParent(self)
At this point, the UI issue was resolved. I did some additional testing and
found that enabling viewrendered.py in @enabled-plugins instead of
viewrendered3.py prevented the UI's border dragging issue in Leo.
Therefore, the root cause seems to be related to vr3. My initial guess is
that there might be an issue with the hierarchy or parent-child
relationship set by vr3. I will investigate this further when I have more
time.
Best regards
