Hi, my name is Zbigg, Iam an architect, I discovered Mypaint ca. 2 years ago and still become a greater fan of this software. I hope to use it for sketches w/my pen tablet /Huion 610Pro/.
Id have a question to developers: present builds: 3.71 lagg /especially x64 build/ a lot on sketching,
this build: 1.2.0-beta.1.113+git.33d1643.dirty had no lags - does it have anything to do w/glib ?
And another issue: once /and only once )) / I ve noticed two devices listed in preferences:
System aggregated pointer
Now I can see only System aggregated pointer - is it ok or might have anyth. to do w/lagging?
Hope Mypaint would start to fly soon, as it looks a fantastic tool to me !
PS. Move my post to relevant topic pls, I suppose I messed a bit ))
I would take a look at our in our Issue Tracker to with the Windows Label and see if there are any the are similar to your issue. Lag has been a continuous problem on our windows builds and were mainly waiting on upstream to fix some of the problems. But I would look there first. If you find that one that matches could you link GitHub issue here so people know where to go if they encounter the same problem?
Sadly our Community Forums are not a for reporting bugs in general. It’s mainly a forum for collaboration and showcasing. I’ll move you to MyPaint Questions for now.
Welcome to the Community BTW. It’s awesome to have an architect here! ^^
Help needed! This one seems impossible for me to reproduce even on crappy hardware and Windows 7 - evidently my kit is just not bitten by this bug, end of story. I’ve tried all sorts, but somebody needs to dive into the code and try stuff on affected machines.
If the issue is happening in both, it shouldn’t matter. Go with the MINGW64 shell if that’s your usual.
You can get/upgrade the deps for each MSYS2 environment with windows/install-msys2-deps.sh just to save time. Of course, if the problem emerged as a result of such an upgrade, a git bisect workflow might be fruitless.
OK, x32 build looks not bad although have some strange issues w/toolbox locking, stopping responding to pen pressure/no drawing at all but cursor moves…, but much less of mentioned lags/above indicated build was really good about this/, mypaint has some problem when switching/dragging between displays - it must have to do w/wintab setting /tablet dedicated display/.
One thing: I was building previously using build.sh script, not just by executing ‘scons’.;
Git produces such thing:
bluecd@computer MINGW32 /c/devel/mypaint
$ git submodule update --init --force
’: invalid ID 89: export: sha1 ': invalid ID 89: export:displaypath
Submodule path ‘’: checked out ‘29dd6c1b815d4725b5185324a51392bb7e2a1c21’
Build x64 also looks quite OK, little lagging on aggregated, complicated brushes and fast drawing, wrench icon inactive on Toolbox even if window focused.
And…whoah !: There are three devices now visible: System aggregated and two HUION tablet pens - why two ??..))
Ive noticed lagging on C_D brushes (which I unfortunately would like the most ))/ AND as I guess starting newly build mypaint WITHOUT 123etc home dir causes mypaint to use most probably default dir on my desktop comp, I’ll check it by removing default installation of any previous mypaint versions.
Update 2: Yes, I think I sorted the problem out: Concept_Design brushes by Ramon, although lovely to me seem to cause lagging: i.e. if C_D brush toolbox is open it causes lagging to ALL the brushes installed, pity…
