[krita] [Bug 423788] Liquify Tool - Utterly Slow Performance
https://bugs.kde.org/show_bug.cgi?id=423788 --- Comment #10 from David REVOY --- Hey Tiar, the fast mode option is as fast in 5.x as it was in 4.x. No regression here. The slow one is the "new" preview mode that appeared for 5.x and was made the default. But this last one has "in layer stack rendering", a cool feature over the "fast mode". Unfortunately, Liquify is very laggy and unusable in this new 5.x default mode. I personnaly set performance to 'Fast' right after Krita 5.x because I know my way in Tool Options[1] and never looked back. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=423788 --- Comment #9 from Tiar --- So what is the conclusion - when using "Fast" preview in Krita 5., is it much slower than Krita 4., or around the same speed (no mater if very slow on higher spacing)? Asking to be sure whether there has been any regression, or is it just a normal (albeit slow) performance and this report is a wish for Liquify to go faster. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=423788 David REVOY changed: What|Removed |Added CC||i...@davidrevoy.com --- Comment #6 from David REVOY --- Hi, I guess these bugs report of @Stig (Rakurri) , @holtein and @Stephen happens because of a more fundamental change of default in the 5x transform tool: the new default 'in stack rendering' that is − indeed− super slow (especially in liquify, especially on recursive groups in liquify too). I had same issue once I started to adopt 5.x. Can you try to go to the "tool options" panel after selecting the "transform tool", and turn the "Preview" setting (on top) to "Fast"? Does it restore the speed you knew on 4.x ? (it should, "Fast" was the setting by default in 4.x) -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=423788 Stig (Rakurri) changed: What|Removed |Added CC||sti-n...@online.no --- Comment #5 from Stig (Rakurri) --- Can confirm on Krita 5 beta3, it is extremely slow on my Windows 10 PC, it takes a very long time to see results of the liquify, the tool most often push the pixels at random it feels like and do not move the pixels around correctly, Krita might even freeze a bit while using the tool. It worked fine in Krita 4.x. This happen on every file. I have a pretty modern 2019 desktop machine, so I think this is affecting a lot of people, I think the bug reports importance should be set much higher than "wishlist" Here is a video of the problem https://imgur.com/a/iXmBffo System Info System Info Krita Version: 5.0.0-beta2 (git a642eb0) Languages: en_US, en, en_US, en, en_US, en, en_US, en, nn_NO, nn, en_US, en Hidpi: true Qt Version (compiled): 5.12.12 Version (loaded): 5.12.12 OS Information Build ABI: x86_64-little_endian-llp64 Build CPU: x86_64 CPU: x86_64 Kernel Type: winnt Kernel Version: 10.0.19044 Pretty Productname: Windows 10 (10.0) Product Type: windows Product Version: 10 OpenGL Info Vendor: "Google Inc."
