Created attachment 169262 [details] Test files for lagging with SVG gradients I experience lagging during typing text when there is an inserted SVG. 1) No problem with other formats: I tested EMF, EPS, JPG, PNG, WMF, ODG, not event with PDF. 2) As I researched the cause of the bug I found that it occurs when there is gradient in the SVG. 3) Affected versions: - LibreOffice 6.4.7.2: There is no problem with real graphics, but with prepared SVG I can cause the lagging. - LibreOffice 7.0.3.1; 7.0.4.2, 7.1.0.2; 7.2.0.0α: All are affected with real graphics and there is an extreme lagging with prepared SVGs. Step to reproduce: - Open a new document - Insert > Insert image... chose one attached SVG file. - Start typing some text after inserted image. The characters appear very slowly with lagging and they usually appear at the same time with a small or big delay depending on how many gradient there is in SVG. Test files: Real graphics: - LibreOffice logo.svg: No noticeable lagging with 6.4, but the lagging is experienced with 7.0+. - Ghostscript_Tiger.svg: Same as above. Prepared SVG's for testing this bug: - svg_objects.svg (There is no gradient, only transparency): No problem. - svg_many_objects.svg (Lot of object without gradients): No problem. - svg_many_objects_with_gradient (Only a few gradients): Lagging in all versions. - svg_many_objects_with_gradient.svg (Lot of object with gradients): Extreme lagging, especially in 7.0+ I tested on Linux (Ubuntu 20.10, XOrg).
I assume this being caused by bug 138068 *** This bug has been marked as a duplicate of bug 138068 ***
Hello Gellért Gyuris, I believe this issue might be fixed now after https://git.libreoffice.org/core/commit/27a4aea50a9efa5c839b0ae2de1f9f14a7782f11. Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ? You can install it alongside the standard version.
Hi Xisco Faulí, I tested, but nothing changed. The described bug is present. Below is the tested version. Maybe this bug is not duplicate of #138068. Please test the "svg_many_objects_with_gradient__test_for_lagging[extreme_lagging].odt" file from the attached test suite. The lagging is very long. As I mentioned above I assume that the lagging is caused by gradients.

I made new tests with never daily builds and on windows too. Result: 1) On Linux the bug is still present. No change in daily builds: Version: 7.2.0.0.alpha0+ / LibreOffice Community Build ID: 41cffc379259fec626a282ca243a9750d96d1c63 CPU threads: 4; OS: Linux 5.8; UI render: default; VCL: gtk3 Locale: hu-HU (hu_HU.UTF-8); UI: en-US TinderBox: Linux-rpm_deb-x86_64@86-TDF, Branch:master, Time: 2021-02-15_20:07:52 Calc: threaded 2) On Windows the bug is not present but not only in development builds but also in stable: Version: 7.1.0.3 (x64) / LibreOffice Community Build ID: f6099ecf3d29644b5008cc8f48f42f4a40986e4c CPU threads: 4; OS: Windows 10.0 Build 19042; UI render: Skia/Raster; VCL: win Locale: hu-HU (hu_HU); UI: hu-HU Calc: threaded Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community Build ID: 2c8ffa41ec8e1ab2af95d5e033a445c17d29cf5a CPU threads: 4; OS: Windows 10.0 Build 19042; UI render: Skia/Raster; VCL: win Locale: hu-HU (hu_HU); UI: hu-HU Calc: threaded So, I assume this is an new bug, not duplicate of 138068 and this is a Linux specified bug. (I cannot test on OSX) I mark this bug to new for now.
