Bug ID: 151686
Summary: rapid flickering and alternating see through layers
Product: LibreOffice
Version: 7.3.1.3 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Description:
The screen rapidly flickers to solid grey/white at the home screen showing
previous documents, or when the right sidebar is visible the flickering is
between the sidebar and the spreadsheet behind it.
When holding the mouse still, it stops, but moving the mouse activates the
flickering.
Steps to Reproduce:
1.From debian-9_x64 start LibreOffice-7.3.1-x86_64.AppImage. Move the mouse
around the screen (inside LibO window) and see no problem.
2.Open a spreadsheet document.
3.Show the styles bar on the right, move the mouse up and down the bar. The top
layer flickers, showing the spreadsheet layer rapidly back and forth.
4.Close the document, then move the mouse all over the previous documents, and
up and down the left side buttons. The entire LibO window flickers to a
grey/white layer.
The flickering speed is too fast to count, 10-30 times per second.
Actual Results:
Screen is stable immediately after starting program. But after opening a
document the window flickers.
Also dragging other windows around, over LibO window, flickers.
The more Previous documents are on the home screen, the longer the flickering
happens, up to 1 whole second, then it goes quiet for a second, then repeats.
Expected Results:
The movement of the mouse should not cause the screen to flicker.
This started with 7.3 because 7.2.5 was fine, and did not flicker.
Reproducible: Always
User Profile Reset: Yes
