Bad display performance (Debian 9) *bug*

[l0rn0r]

Hi,
just found Onlyoffice DesktopEditors - looks great!
Now I made the following installation on Debian 9.7 (Kernel 4.9.130-2, amd64) with lightdm 1.18.3 and/or Cinnamon 3.2.7:
DesktopEditors 5.2.83.480 (I'm aware, this version is released for Debian 8, but I tried :))

Current behaviour / step-by-step:

• Starting DesktopEditors (through terminal) as non-administrative user
• It starts and I can open files - in my case a docx-file.
• But once I opened a file and maximized the window, scrolling is not fluent at all and the screen is hopping all the time. Also opening the menu looks horrible (see screenshot). Plus I have no access to my fonts (stored at ~/.fonts).
  
• When the window is not maximized, the performance is better and workable with...
• There are no error messages given at the terminal.

Behaviour when starting DesktopEditors as root:

• Meant before, it is a permissions problem - but now after some minutes working with DesktopEditors as root, display performance got bad too...
• When starting as root in terminal, I get the following error:
  QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
• But I do have all my fonts available. :)

About my display settings:
3840 x 2160 resolution, UI-scaling 2x (Hi-DPI, doesn't change if I set it to 1x)

Thanks for your work - and maybe for any hint on me doing something wrong...!

Hi, this is known bug 40526 and currently we don't know reason of this behaviour (we don't think it's * XDG_RUNTIME_DIR related)

[l0rn0r]

Sorry, I did not see bug 40526 - so feel free to close this issue!
Thanks for working on it!

[ShockwaveNN]

@l0rn0r No. Sorry, I forgot to mention that 40526 is issue in our internal tracker, I leave your bug open until issue is resolved.

I'm experiencing the same issue:
white flickering elements/zones when doing sth.

When i make the window smaller, it gets better.

Same problem here on debian 10 with a 4k display and a 200% scaling.
I tested with both wayland and xorg and the problem is the same.

I too still have the issue even on the latest release. Changing scaling did not help either.

I'm experiencing exactly the same issue with Manjaro (GNOME). If I run Onlyoffice maximised, the screen flickers every time I type something or start a new paragraph. When the window is smaller this behaviour dissappears and all is stable

[ShockwaveNN]

We think this issue is fixed (as far as I remember - this is issue from ChromiumEmbeddedFramework) and fixed by update of cef
We'll release update with v5.5.0 (currently no ETA of release)

@ShockwaveNN
Hi,
I updated to 5.5.1.78 and can confirm that this issue is fixed for me. (Arch, Linux)

Many thanks, that was an annoying bug in combination with tiling 😄

[ShockwaveNN]

@Coffeetron glad to hear.
I'll close this issue, but feel free to report if something similar occured
