dde-file-manager shrinks on enabling picom

[bonecountysheriff]

Platform

Arch Linux x86_64

Environment

i3-gaps

picom version

v7.5

Configuration:

default

Steps of reproduction

1. Install i3-gaps and deepin-file-manager from the official arch repositories.
2. Start i3-gaps using xinit or lightdm
3. Run dde-file-manager.
4. Now, start picom.

Expected behavior

The gap size should be as expected.

Current Behavior

current gap-size = expected gap-size + half-an-inch
If picom is killed by hand, the gap size goes back to normal.

Other details

As far as I know, other deepin applications look just fine with picom.
(I clipped out a small portion at the bottom of the images, it contains the i3-bar, nothing else. This is why the bottom gap looks uneven.)

[bonecountysheriff]

Just the window size. Transparency works just fine.

Expected Behavior

(without picom)

Current Behavior

(with picom)

Application on the left: deepin terminal
Application on the right: deepin file manager

Like I said, only the file manager has the issue. Other deepin applications work as expected.

@georgebush422 the file manager probably behave differently depends on whether a compositor is present.

Can you raise this problem to the upstream?

[absolutelynothelix]

@georgebush422, i guess @yshui meant the dde-file-manager upstream, not the compton upstream

[yshui]

@mighty9245 yes.

@georgebush422 Sorry, I wasn't being clear. Can you raise this to dde-file-manager upstream?
