Composer bug in my forum & my desktop with a bigger-blocking plus icon

The picture shows my problem. The plus icon in the composer is bigger and blocking in the wrong place. I thought it was my own forum’s problem, but when I am editing here, it shows that in this official forum, the composer has the same problem. Can it be my Edge explorer?

This is iPad, latest 18-serie and DiscourseHub:

So, it looks like it could be a browser question.

Yeah, I know that, it’s ok on my phone too. So is there something I can do with my edge browser :sob:

looks like RTE composer in horizon. i can’t can’t seem to get a repro on any device or browser i use (iOS, MacOS or Linux) but i don’t use Edge, so possibly to do with it.

Do you happen to be on Chromium or Opera? On Linux Mint here, I can’t reproduce the “big blocking plus icon” in Firefox - it only shows up for me in Chromium-based browsers.


A few quick things that did change the symptom on my end:

  • Toggle hardware acceleration (on/off) in Chromium/Opera, then restart.
  • Try launching once with --disable-gpu to see if it’s the GPU path.
  • Check chrome://gpu for any compositing/accelerated canvas issues.
  • If you’re on Wayland (say you’re using Edge on Linux), test --ozone-platform=wayland vs x11 (or vice-versa).
  • Reset any zoom/scaling quirks (browser zoom 100%, OS fractional scaling off).
  • Try with all extensions disabled (Incognito with no extensions is a quick check).

it helps to share:

  • your Distro/DE (e.g. Mint Cinnamon), kernel, and windowing system (X11/Wayland)
  • Browser + version (chrome://version), and whether hardware acceleration is on
  • GPU + driver (mesa/NVIDIA proprietary)
  • Repro steps and a short screen capture

FWIW I’ve sent reports to Google/Opera already; Firefox on Mint renders the composer normally for me, so this looks confined to the Chromium path.

I can provide some information here: Win10 22H2 19045.6332, Edge 140.0.3485.66.

I checked the element, and I found the “options“ may be the reason. When I delete that, the shape can be normal, and the parameters ‘width‘ and ‘left‘ are questionable.

Just confirming, does this happen in safe mode as well?

Finally!!I found the reason. It’s one of my extension called ChatsNow. Turn it off and the button will be normal.:grinning_face:
