gnome-calculator with transparent formula entry box

[SilvioBandeira]

I have a notebook and desktop running Ubuntu 16.10 with Unity... in both machines the gnome-calculator shows a transparent formula entry box.
Installing the new version 2.23.4 solved the issue in the notebook but not in the desktop.

I have similar error, however opening top-left menu fixes it until window closing.

I also experienced this issue in 16.10 (also with Intel graphics), as noted in a comment on another bug[1]. But, for what it's worth, I don't experience the issue anymore in 17.04.

Same issue here, screenshot attached.

Status changed to 'Confirmed' because the bug affects multiple users.

do you use xim/have a ~/.xinputrc config? that looks similar to bug #1620806

[SilvioBandeira (silviobandeira)]

Yes, I confirm that the existence of the line below:

run_im xim

in the file ~/.xinputrc causes the problem... tested in my notebook. If I put "ibus" instead of "xim", and log out/in again, the problem disappears.

Same here - solved for me.

Switching to ibus fixed it

Switching to ibus solved the problem.

Calculator worked flawlessly in Advanced mode in 16.04 (and before). Upgrade to 18.04 and this bug appeared (the bionic desktop visible in the display window). Using the calculator produced overtyped characters and weird gridding between the numbers displayed (see attached). Switching from xim to ibus seems to have solved it.

Calculator display showing bionic desktop capture in display area (no longer transparent) with overtyping and gridding in the number display.

Switching to ibus solved the problem.

This also fixed a problem of getting overlaid text when scrolling the details of an ongoing backup with Déjà Dup.
