Comment 17 for bug 1854183

Description:
After opening a CSV in Calc (Text import) instead of opening the main Calc window, the space where the window is supposed to be, shows a "frozen" image of whatever was under the window before opening it. Calc menus and buttons still work, but nothing is visible. It'a a bit hard to explain, but the attached video is self explanatory.

The only error I get is:

(soffice:28076): Gtk-WARNING **: 12:06:36.708: infinite surface size not supported

I'm using Ubuntu MATE 18.04
- This happens when using Compiz, but not when using Compton
- This happens in LO 6.2 & 6.3 but not in LO 6.1.5
- This happens when Calc's window starts maximized, but not when it starts unmaximized
- This happens when using libreoffice-gtk3 but not when using libreoffice-gtk2

Steps to Reproduce:
1. Enable Compiz
2. Open a CSV file with Calc
3. Click "OK" on the "Text import" window

Actual Results:
Whatever was on the screen stays frozen, as if it were a static image, and the Calc window were invisible. Moving the mouse around and clicking seems to open Calc menus.

Expected Results:
Calc's main window should open normally

Reproducible: Always

User Profile Reset: Yes

OpenGL enabled: Yes
