Bug ID: 104474
Summary: Cell graphics rendering glitches with Freezing
Rows/Columns or Split Windows
Product: LibreOffice
Version: 5.2.3.3 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Description:
When there are frozen rows/columns or split windows enabled, the contents of
cells outside the frozen area or "top" split window exhibit graphical glitches.
In particular, the old contents of a cell are not "cleared away" when writing
new contents. The new contents appear on top of the old contents creating a
graphical mess. The underlying, actual value of the cell IS changed, however.
The graphical glitch goes away when you leave the cell (e.g., after pressing
"Enter")
Steps to Reproduce:
1. Open a new Calc document
2. Freeze the first row
3. Type "123" into cell A2, but do NOT press 'Enter' or leave the cell
4. Press 'Delete' three times to attempt to erase the "123" (again, do not
leave the cell or press 'Enter')
5. Type "456"
Actual Results:
When pressing 'Delete' in step 4, the "123" do not graphically disappear
(although the data contents of the cell ARE updated). When typing "456" in step
5, the "456" appears on top of the previous "123" creating a jumbled graphical
mess (but note, again, the actual VALUE of the cell is properly updated).
Expected Results:
Whatever is being typed, the current updated contents of the cell are displayed
with no graphical irregularities.
Reproducible: Always
User Profile Reset: Yes
Additional Info:
Additional Hardware/Software Info:
- CPU: Intel i7 Broadwell (5th generation)
