Created attachment 124561 [details] screencast Running the open-source "radeon" gallium X.org drivers with a Radeon HD 7770 (radeonsi chipset) on Fedora 23 64-bit, with LibreOffice 5.1.1.x and 5.1.2.x downloaded from the LibreOffice website, some of the LibreOffice dialogs show broken text glyphs. See attached screencast. This is with experimental features turned off, and the traditional UI backend (not the GTK3 one). Couldn't find a way to try out the GTK3 version from the RPMs downloaded from the LibreOffice website (even if I check "Enable experimental features")
I'm getting this bug with the following graphics: *-display description: VGA compatible controller product: Bonaire [FirePro W5100] vendor: Advanced Micro Devices, Inc. [AMD/ATI] physical id: 0 bus info: pci@0000:03:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=radeon latency=0 The OS is: Description: Ubuntu 16.04 LTS Release: 16.04 Codename: xenial See: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1575000
I also can confirm this. I run Debian Testing/Stretch, with LibreOffice 5.1.2.2 from the repos. *-display description: VGA compatible controller product: Kaveri [Radeon R7 Graphics] vendor: Advanced Micro Devices, Inc.

The issue disappears when OpenGL is switched on.
confirmed in comment 2
I just installed 5.2.0.0.alpha1 (Build ID: 902b28a39528b6c92602e9b521a1d0861be1caf9) and I cannot reproduce this bug there. It would be great if someone could confirm this.
Jean, Walter, please could you test it with dev version? You can download it here: http://dev-builds.libreoffice.org/daily/master/ Thank you
raal, I installed LibreOffice 5.2.0.0.alpha1 in my affected system and the artifact is gone, no font glyph corruption any more.
Walter and "D" thanks for testing. Closing the bug.

Just a question, do we know if this is fixed in the 5.1 branch?
I have the very same issue on an intel skylake system under openSUSE Tumbleweed. My Libreoffice version is: Version: 5.1.3.1 Build ID: 10m0(Build:1) CPU Threads: 4; OS Version: Linux 4.6; UI Render: default; Locale: en-US (en_US.UTF-8)
Is there a specific patch I could refer to, which could be applied for 5.1 series?
with 5.2 beta1 issue is resolved here for intel skylake too. Thanks.

If someone wants to verify the fix is in 5.1 branch: http://dev-builds.libreoffice.org/daily/libreoffice-5-1/?C=M;O=A
The bug is still there in 5.1.4.1 according to this comment: https://www.reddit.com/r/libreoffice/comments/4ljqr8/i_have_strange_unreadable_fonts_in_some_of_los/d3z9gwp
So I solved my problem by removing a faulty Tahoma font, as I think it gets some priority for UI font if available.
Caolán, any thoughts on how this could still be occurring in 5.1.4.1?
Looking into my history of a very similar sounding bug we had in fedora, then I debugged this for ages and I think its a bug somewhere else outside of LibreOffice, and its only happening on the X+cairo route. I have a bodge for it which I see didn't make it back to 5.1 but did to 5.2. What worked for me in Fedora is available for review for backporting to 5-1 at https://gerrit.libreoffice.org/#/c/26087/
Caolán McNamara committed a patch related to this issue. It has been pushed to "libreoffice-5-1": http://cgit.freedesktop.org/libreoffice/core/commit/?id=c55d703ea00de67793765f8da7ca17dfb54281fc&h=libreoffice-5-1 Related: tdf#99446 cairo text + xrender bodge It will be available in 5.1.5. The patch should be included in the daily builds available at http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: http://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.
