Description: No progress bar saving to PDF with Skia Metal; fine with Skia/Raster Steps to Reproduce: 1. Open https://drive.usercontent.google.com/download?id=1UacZYIhlo505D3S3nGeWA6gY2uHndP1P&export=download or some other large document 2. Click Export PDF and export. No progress bar Actual Results: No progress bar for pdf export Expected Results: Progress bar while saving pdf Reproducible: Always User Profile Reset: No Additional Info: Version: 25.8.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 141f3fd15633803afa720837405a0bacbc2726cb CPU threads: 8; OS: macOS 14.7.1; UI render: Skia/Metal; VCL: osx Locale: nl-NL (nl_NL.UTF-8); UI: en-US Calc: threaded fine with Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 5682e1d4145c26fc8021879df0543d5aeacf9c83 CPU threads: 8; OS: macOS 14.7.1; UI render: Skia/Metal; VCL: osx Locale: nl-NL (nl_NL.UTF-8); UI: en-US Calc: threaded
I can reproduce this bug in the 2024-12-24 master nightly build: Version: 25.8.0.0.alpha0+ (AARCH64) / LibreOffice Community Build ID: 2305fe302e12c4256e452589e2533772d4213e59 CPU threads: 8; OS: macOS 15.2; UI render: Skia/Raster; VCL: osx Locale: en-CA (en_CA.UTF-8); UI: en-US Calc: threaded The progress bar works fine in LibreOffice 24.8.4 release so I will test if my commit 0ddd9f7e055a0c1ecb120de3e40c3fdb8373e9dc is the cause of this bug. Unfortunately, I have to do a full clean build. If I run my local debug build, exporting PDF does show the progressbar when using Skia/Metal. But, the export takes at least 20 or more seconds compared to no more than 5 seconds in today's master nightly build.

B) The Progress bar is indeed lacking in more cases. It's not specific for PDF export. Opening a large PDF in Draw. Saving big document Writer document and so on FWIW: Opening a file from Start Center does show the progress bar itself. It doesn't give much feedback; it's not really progressing, though

Skia/Metal is very finicky as to the flush rate (not too many and not too few times per second). I already have a "mbForceFlush" flag. I think I'll need to add a "mbScrollbarForceFlush" flag and just plow through all of the "don't flush now" conditions.

Patrick Luby committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/1846448d81aab9812410a30303c0c36a41a825b6 tdf#164428 Skia/Metal needs flush after drawing progress bar It will be available in 25.8.0. The patch should be included in the daily builds available at https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: https://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.
I have committed a fix for this bug. The fix will be in tomorrow's (26 December 2024) nightly master builds: https://dev-builds.libreoffice.org/daily/master/current.html Note for macOS testers: the nightly master build installer does not overwrite any LibreOffice official versions. Instead, it will be installed as a separate application called "LibreOfficeDev" in the /Applications folder. Because this is a "test" build, you will need to do the following steps before you launch the LibreOfficeDev application: 1. Go to the Finder and navigate to the /Applications/Utilities folder 2. Launch the "Terminal" application 3. Paste the following command in the Terminal application window and press the Return key to execute the command: xattr -d com.apple.quarantine /Applications/LibreOfficeDev.app
