When skia is enabled in Options->View, all toolbar and menu rendering is laggy. Trying to pop-down a menu or hover over an icon results in a delay measured in seconds. Disabling skia results in normal speed (fast, not noticeable delay)
Please post content of Help -> About dialog. And content of the skia.log, on Windows in the %APPDATA%\LibreOffice\4\cache folder.
In addition to the info asked above, does it help if Skia is kept enabled but is forced to software rendering?
Will do; it's an intermittent bug and I have now re-enabled skia and will posr logs etc when it next happens.
[Automated Action] NeedInfo-To-Unconfirmed
I can confirm that (so far) skia software rendering fixes it. Details as requested: ------ skia log ------ RenderMethod: vulkan Vendor: 0x8086 Device: 0x3e9b API: 1.2.154 Driver: 0.402.743 DeviceType: integrated DeviceName: Intel(R) UHD Graphics 630 Blacklisted: no ------ version info from About ------ Version: 7.0.3.1 (x64) Build ID: d7547858d014d4cf69878db179d326fc3483e082 CPU threads: 12; OS: Windows 10.0 Build 19041; UI render: Skia/Vulkan; VCL: win Locale: en-AU (en_AU); UI: en-US Calc: CL
...another observation: the FIRST time I run LO after turning off software rendering it works OK. When I restart LO the second time (still with software rendering unchecked), it runs slow again.
Can you please check in the About dialog that software rendering is really used when you encounter the problem ("UI render: Skia/Vulkan" vs "UI render: Skia/Raster")? Also, is there any pattern to it working the first time and not the second time (e.g. what is the state the 3rd time)?
When it's working fine, Skia/Raster. After unchecking "force s/w rendering", "Skia/Vulcan" Note: 1. Skia/Vulcan on first restart, and performs OK 2. Second + restart, performance is laggy 3. The lag applies to menus AND tooltips (don't think I mentioned those before)
This could be a problem with your graphics drivers. Can you please try updating them to the latest available version?
No response, closing. If you still have the problem, please reopen and provide the requested information.
Sorry forgot to reply; latest drivers a month ago made no difference. Will try again after latest windows update.
Are you trying latest Intel drivers from your computer vendor (HP, Dell, whatever) or the actual latest Intel drivers directly from Intel?
I can now confirm that with the latest windows update, latest Intel drivers (from Intel), latest NVidia drivers and LO 7.1.2.2 it all seems to work with skia not checked. Info below: Version: 7.1.2.2 (x64) / LibreOffice Community Build ID: 8a45595d069ef5570103caea1b71cc9d82b2aae4 CPU threads: 12; OS: Windows 10.0 Build 19042; UI render: default; VCL: win Locale: en-AU (en_AU); UI: en-US Calc: CL
But the bugreport is about Skia/Vulkan, so what is the status there?
Ooops...lol...yes...also fine!
Luboš Luňák committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/eb10c4dd78703f1af501db14a0c72ef5d1b74be4 blacklist intel 0.402.743 vulkan driver (tdf#138729) It will be available in 7.2.0. 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.
@Luboš, * On a Dell Windows 10 4K HiDPI laptop with driver (27.20.100.8935) RenderMethod: vulkan Vendor: 0x8086 Device: 0x3e9b API: 1.2.154 Driver: 0.402.743 DeviceType: integrated DeviceName: Intel(R) UHD Graphics 630 Denylisted: yes did a driver update (27.20.100.9466) RenderMethod: vulkan Vendor: 0x8086 Device: 0x3e9b API: 1.2.170 Driver: 0.402.1274 DeviceType: integrated DeviceName: Intel(R) UHD Graphics 630 Denylisted: no Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community Build ID: f616d96bd8ce8986e4cc204953db0467e6060b5c CPU threads: 12; OS: Windows 10.0 Build 19042; UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL of course no deny list for this current driver. But not clear to me if this also needs to be added to the Skia deny list. Overriding the Skia deny list for the 0.402.743 driver and using Vulkan had no issues. I did note some issue with handling the view port buffering when Writer smooth scroll was enabled with either driver and this GPU. Filing another issue for that.
