Description Guro Daniel Pagulayan 2025-11-08 11:23:21 UTC
Description:
OS: WIndows 11 with latest update
LO Version: 25.8.2.2 (also same experience on LO 25.2.7)

On Impress only (not on Calc or Writer), when moving a selected phrase that had been formatted (say bold, Ubuntu font), to any location in a paragraph or bullet point (in the same slide), the program hangs. Result is a forced stoppage via Task manager. When office restarts, it asks to recover files that were open at the time the hung-episode happened.

This was e reported on asklibreoffice. Last message prior to suggestion to report bug as follows:
"Hi Earnest AI,

I tried safe mode.
Skia settings: https://drive.google.com/file/d/163zcNrnSPQF53NYP9VojB0ohXY-ZAm_c/view?usp=drive_link 1

Hung event video: https://drive.google.com/file/d/1vvy5CQrLBQO9twzwmCwMP66m-a_L5sX3/view?usp=drive_link 1

Same hung event when running LO on safe mode.

So, I went ahead with resetting the user profile manually and ran LO on both regular and safe mode. Same hung results on each mode.

I also fired up my win 10 drive, reset win OS to factory state, updated win 10 and drivers, then reinstalled latest LO, then checked for LO updates. I then restarted win 10, rechecked for WIn10 and LO updates once more.

After that, I ran LO on both safe mode and regular mode. Same hung results. "


Steps to Reproduce:
1. Create a bulleted phrase
2. Highlight entire text of bullet point
3. Drag and drop the highlighted text


Actual Results:
After releasing the mouse click at the intended transfer site, nothing within the  Impress window is clickable. 

To reload Impress, need to end the session via Task Manager and, then, run LO again.

Expected Results:
Moved the highlighted (selected) text to the intended destination


Reproducible: Always


User Profile Reset: Yes

Comment 2 Sarah Lim 2025-11-14 13:30:40 UTC
will just mention here that this is reproducible in 

Version: 25.8.2.2 (X86_64)
Build ID: d401f2107ccab8f924a8e2df40f573aab7605b6f
CPU threads: 12; OS: Windows 11 X86_64 (build 26100); UI render: Skia/Raster; VCL: win
Locale: en-US (en_FI); UI: en-GB
Calc: threaded

but works fine in 26.2.0.0.alpha0+

Bibisected the fix with win64-26.2 to 23afeaedf4d4a03943338fc39ae41f5c423e5997
tdf#168431: Release solar mutex when sending window message to main thread

The fix is also in 25.8.3, which is already released.

I noticed that the requirement for reproducing was to have the dragged text be formatted in bold.
