Description

And after using dbeaver for a while, it sometimes causes a crash.

does it work fine on sway?

[lufjo]

does it work fine on sway?

yes, all good on sway

[MightyPlaza]

what about an older version of hyprland like v0.39.0? can you send a video with damage_blink enabled

[lufjo]

On older versions there was no this issue, I forget what version this issue is from, likely from v0.40. And now build or downgrade that old version is more or less difficult. With damage_blink enabled:

Regression since 6967a31450441fc5605c05db6f65505dace4b263

[vaxerski]

it's because of a hack that I made to prevent qt flickers. Fuck my life. Removing it fixes this, but makes qt flicker again.

[lufjo]

@vaxerski Seems this issue is back on 0.42 release.

[vaxerski]

-git too? Can you bisect?

[lufjo]

-git too? Can you bisect?

@vaxerski yes, git too. Regression: b0a70f63e

[vaxerski]

I hate my life :)

[romanstingler]

can you try the latest DBeaver Version 24.2.0.202409011810 and yay -S aquamarine-git hyprlang-git hyprcursor-git hyprutils-git hyprland-git --overwrite="*"

I use DBeaver on a daily basis, and haven't seen it for a long time

[UjinT34]

Flickers with dbeaver 24.2.0.202409011755 and 9b54342baa27d8de0460e1103ec4c3cc65592ed8. Less severe than it was before the previous fix. Dbeaver itself doesn't crash for me but it makes hl leak memory until it runs oom and crashes. About 50-300mb every time dbeaver renders something new. Seems to depend on dbeaver's window size. Memory isn't really leaked, it is released back as soon as dbeaver is closed.

[brisk84]

Can confirm. I have this issue on DBeaver 24.2.1.202409072322 and Hyprland 0.43.0. My config is 12450H with iGPU.

[kareemAbd0]

I thought this was a 43 milestone, had to download plasma to continue work.

Any progress so far?

[vaxerski]

I'll remove the milestone - not working on this atm (I've spent a few hours a while back and couldn't find what was wrong)

Feel free to revert that one faulty commit, but it does break some other things (e.g. hyprpicker)

[LorenzoBettini]

As in the linked issue, this problem affects any Eclipse-based applications, like DBeaver and the Eclipse IDE itself.

I'd suggest @lufjo change the title of the issue to mention "Eclipse" or "Eclipse-based", so that the issue can be easily found.

[rizqicy]

FYI this workaround make it less pain to work with dbeaver at the moment (tested on my side and it works).

[asgmojtaba]

the most annoying thing it's not flickers but memory leakage that grows continuously (on hyprland process not dbeaver) while working with dbeaver. changing theme reduce flickers but don't do anything about memory issue.

My dirty workaround is forcing dbeaver to use X11 by changing Exec segment of it's desktop file to following:

...
Exec=env GDK_BACKEND=x11 dbeaver
...

Yes u lose all fancy feature of wayland (in my case HiDPI support!)

hope somebody fix this soon. (I have no idea about hyprland itself 😟)

[LorenzoBettini]

Yes u lose all fancy feature of wayland (in my case HiDPI support!)

@asgmojtaba for scaling in X11, I blogged about a few tricks here https://www.lorenzobettini.it/2024/09/eclipse-in-hyprland-0-43/

XD thanks.. and i came here from blog... guess it's xwayland then..

[UjinT34]

Why dropCurrentBuffer(); inside commitPendingState? https://github.com/hyprwm/Hyprland/blob/bb160cfe377da2d2b2e4431a3399fa60114f3911/src/protocols/core/Compositor.cpp#L451

With this drop old buffer is (always?) empty https://github.com/hyprwm/Hyprland/blob/bb160cfe377da2d2b2e4431a3399fa60114f3911/src/protocols/core/Compositor.cpp#L88 and dbeaver has this flickering issue which causes HL to "leak" memory (probably video memory only, easier to test with integrated gpu without dedicated ram). Removing that drop solves this issue and doesn't seem to cause any other issues.

[vaxerski]

launch hyprpicker after you remove that drop and it won't render

[UjinT34]

hyprpicker works for me without that drop...

How do signals and listeners work? Can something passed to registerListener be called without emit? IHLBuffer::hlEvents are never emitted.

[vaxerski]

nope

IHLBuffer::hlEvents are never emitted.

they are in aq

[vaxerski]

ah, maybe that one does, this part is very finnicky and like every line has been through 4 revisions because random things would break. Fun.

Perhaps this one was there to fix the xwayland leaks xd
