Bug ID: 167277
Summary: With Skia/Vulkan enabled, line numbers aren't updated
while scrolling in Basic IDE
Product: LibreOffice
Version: unspecified
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: BASIC

Screencast of the problematic scrolling
Enable Skia/Vulkan.
Open attachment 201438, which has rather long Basic module.
Open that module in the Basic IDE.
Make sure that the line numbers are shown (View->Line Numbers).
Put cursor to the top of the module text, and press and hold Page Down button
to scroll to the bottom.
=> notice how the line numbers are not updated, or updated with large delays,
until you finish scrolling.
Similar thing happens when scrolling by dragging the scrollbar thumb with
mouse.
When using Arrow Down key instead of Page Down, the update of the lines is also
broken, but additionally, some drawing artifacts appear in the line numbers
area.
The area with breakpoints is also affected.
This problem does not happen with Skia/Raster, or with Skia disabled.
The problem makes is more difficult to quickly scroll to a given line number
(or to a breakpoint) using the mentioned ways (yes I know that there exist line
number indicator in the status bar, that is updated OK; and that there is a Go
To Line dialog; but their existence does not disqualify the described problem
as a bug; and these existing means do not allow to "go to a breakpoint").
