Is it possible to share an example or the file shown in the screencast demonstrating the issue
(In reply to Telesto from comment #2) > Is it possible to share an example or the file shown in the screencast > demonstrating the issue Sure. Anyway, I experience this issue to some degree also with other graphical elements like tables.

I confirm a slowdown scrolling around the image on Windows with GDI Version: 6.4.0.0.beta1+ (x64) Build ID: 20be5cd0bdc57d812bf34a2debfe48caa51de881 CPU threads: 4; OS: Windows 6.3 Build 9600; UI render: default; VCL: win; Locale: nl-NL (nl_NL); UI-Language: en-US Calc: CL and in 7.1 slightly faster) FWIW, do you also have an table example (probably something different)
Also in 4.4.7.2 but not in LibreOffice 3.5.7.2 Build ID: 3215f89-f603614-ab984f2-7348103-1225a5

Thank you.
@Xisco But of 2 bugs in 1.. The initial report I confirm on Win (GDI) Table scrolling is fine for me (Win). Would mind to give it a try https://bugs.documentfoundation.org/attachment.cgi?id=162542
I also get this problem, even when a document contains no images. As I find LibreOffice much more accessible than Word, especially as it has drop-down menus, I really do not want to return to MS Word, but the poor rendering is becoming increasingly difficult. I don't understand why it should be doing this as I have a very good 4k graphics card and display, and have tried hardware acceleration, but the problem persisted. Sarah
No repro Version: 7.6.0.0.alpha1+ (X86_64) / LibreOffice Community Build ID: f97a7b965be154824e108802b386e3132b0a237a CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win Locale: fr-FR (fr_FR); UI: fr-FR Calc: CL threaded
(In reply to Sophie Sipasseuth from comment #13) I still repro with Skia disabled (so GDI mode) Version: 7.6.0.0.alpha1+ (X86_64) / LibreOffice Community Build ID: 389a8d52d9961f89c0b2847b30ee1ca59a8fdc80 CPU threads: 4; OS: Windows 6.3 Build 9600; UI render: default; VCL: win Locale: nl-NL (nl_NL); UI: en-US Calc: CL threaded No issue with Skia/Raster on Windows
Yes, it is true with Skia disabled, the scrollbar runs with jerks.
Not a regression, already seen in 3.5.0. Depends on the zoom level. Try single page view at 75%, no lag.
