Room description window constantly oscillates between one line and two lines.

[dreirund]

I just compiled Quaternion from this git repository using this modified recipe, and I opened a room that has a description and the description window constantly oscillates between two lines, one line window height and scrollbars and one line, two lines window height and no scrollbars.

I attach a video recording this (the overlayed windows are there to censor sensitive information).

There's an inherent problem with text layout if scrollbars are allowed to disappear when they are not needed; but showing them at all times is not the best option in this case either. I could say it's a problem in QML but I think I don't make it easier with my dynamic height adjustments. I'll see if it can be helped.

Btw, I took a look at the recipe, and I have a couple of comments on it:

• It's more accurate to build the version 0.0.97~beta.git* if that's allowed by your distribution rules; although, admittedly, the difference from 0.0.96.1 is so far minimal
• -DBUILD_WITH_QT6 is no more supported because it's always Qt 6 now; you can safely drop it
• -DBUILD_TESTING=OFF works on libQuotient but not on Quaternion; as I understand it, you build Quaternion with an out-of-tree libQuotient (which is usually recommended for distro packages), and that case, this option has no effect

Can you check if this branch fixes the problem?

Can you check if [this branch](https://github.com/quotient-im/Quaternion/tree/kitsune/fix-room-header-layout-havoc) fixes the problem?

No, it still oscillates. (To double check for you if I used the correct source: `git log` after checkout shows as last message

-- %< -- commit bead28b (HEAD -> makepkg, origin/kitsune/fix-room-header-layout-havoc) Author: Kitsune Ral <censored> Date: Mon Nov 11 20:32:12 2024 +0100 Timeline: Don't mess with room header padding Recalculation of padding depending on whether the scroll bar is there can easily break the already fragile layout logic, bringing minimal benefits in return (it was made to avoid the text ending up under transient scrollbars that are overlapping with the client area - but transient scrollbars disappear after scrolling anyway). Hopefully fixes #916.

Yes, this is the correct commit. Then I'm afraid I have to ask you to change the window or left dock pane size a bit, as a workaround. This may also be a problem with a specific Qt theme, or, as I said, an inherent glitch of the code in Qt that lays out text in a text area. I might try to take it to Qt issue tracker but that's almost never a fast track.

@dreirund you may try to check the same branch again (commit 62ae4e4), I'm now sizing the text area closer to Qt's own practices.

@dreirund you may try to check the same branch again (commit 62ae4e4)

Seems to work now (for the room where I had this issue).

I don't see any scrollbars now, and the area stays constant size (one line in this case).

Off-Topic: Any way how I can verify the quaternion session?
