Do you really think that performance issue is really (ONLY) due to Dyntopo itself?
I don't think so, at least not totally, just parcial, as it's an algorithm that may be improved SO MUCH with some love and coordination/help if needed.

Hi @Jeroen Bakker (jbakker) I can't reproduce it now with last 2.82 beta and last AMD drivers, glitches are gone!

Another option could be add all brush tools to the list, and when switching to a brush via shortcut, change to the active brush of that brush type/tool instead of change to the default brush, that way it will support any brush the user have as it will change to the "active" brush of that tool. I hope to explain it well.

the user should be able to choose any brush preset to use as the Shift mode, not just the default preset for the tool.

Applied revision by @Antonio Vazquez (antoniov)

Now it searches for an alternative smooth brush when "Smooth" brush isn't available or is renamed.

This was a driver related issue so I close this one. It's actually working fine.

@Adam Preisler (Alphisto) Uh? Disabling addons was just to make time, I could stay without doing anything and it will crash, doing several things over preferences wasn't the issue or the cause of the crash
Anyway, I think I don't have the issue, at least can't reproduce it now (probably cause the new Windows November update(?), idk...), so yeah, better to close this, thanks!

@Paul Kotelevets (1D_Inc) Here's a more automatic way with notes but better interpretation of quads to follow the flow of the models, made time ago for sculpt (with some modifiers on it), as it is now it's not really useful for retopo but could be kinda useful with some adaptations and implementations like a new note tool that works (create quads) in real time + radius setting, or quick post-edit tools and some other options and widgets. But doesn't Retopoflow have something similar?

I can confirm this, also adding to this issue same happens to me when making addons that for example use brush data, If I change some setting over other area (properties, headers, toolbar...) Panels don't update and you have to mouse over the panel to force an update, that's an issue from so much time ago and hope devs can dig into it soon...

Also I can see some of the vertex connections that occur inside the mesh in a few of the examples in that image. Look in wireframe view mode.
I report that bug here:
https://developer.blender.org/T70292

@Pablo Dobarro (pablodp606) Yes, I didn't realize if you don't say it, it shows a warning, probably something more "invasive" like a popup window will be the thing atm..

@Abid Maqbool (cto.abid) Oh! thanks for the clarification. I close this haha :)

Can't reproduce this with Blender 2.81 build from 14th August later build and with Blender 2.80 last build

Hi... I know thi is closed but still having this issue.
I updated drivers and in release notes of 19.8.1 version ....

I confirm this is happening. Crashes with just clicking at edit mode

Ok, today is working :| , slowly (almost crash) but not crash at the end. I updated drivers to new update that is so recent as @Philipp Oeser (lichtwerk) proposed, I don't know if it was that but yesterday, trust me, every time I tried was a crash, not only a uv spehere, also a cube and so on... So I'll close this thing at the moment. Thanks all for your answers and your time :)

Addons are fine @Germano Cavalcante (mano-wii)

@Jeroen Bakker (jbakker) Hi, yesterday I reported this https://developer.blender.org/T68519 and looks like an issue from AMD drivers with Windows 10 May update. I don't know if it's related to the issue reported here in some point (or not), but I wanted You to know about it, just in case it turns out to be like that.

Is nice to see is not a problem with Blender. The file is too new, I didn't open it before. Looks like previous versions of this driver have the same issue.... Probably too old drivers are the good ones for this issue, release notes of 19.7.2 don't have this line but that corruption is affecting too in some ways like opening the OS and a green flash appears, I hope AMD will fix that... Anyway, the gpu is new so I can return it if this will give me problems, is more easy than reinstall all things on my computer with other (compatible) windows version and so on.

@Jeroen Bakker (jbakker)

I still have this problem with 2.81. Also updated to new driver version of AMD.

Sure! @Sybren A. Stüvel (sybren)

I see the 3rd one as something so needed and one of the reasons I started this https://github.com/jfranmatheu/Blender_NewSMUI

Yeah, as I said I reopen the file and it's ok (in most cases, sometimes it opens bad), no issues, and then with some time editing and working around... it comes back by magic, at least this is what is happenning to me (literaly). And always is trigger because of ''in front'' option in solid and textured display mode, BUT not always happen or happen if you switch to other workspace. That's the all thing.

@Germano Cavalcante (mano-wii) Well I can provide this file and... sometimes it triggers... but when you reopen Blender it's ok again (in most cases). So the fact is if you open it and all it's ok (at least at the start)... In this case probably will means a lack of compatibility with amd(?) If it's useful for You, I can try to run Blender with the command line for gpu. --debug-gpu-force-workarounds or any other to see what happens.

Have this issue too, I note that it disappears when activating the option to display modifier in edit mode (like Mirror modifier)

Hi, I verify all is because of the intel's driver. I manage to update it. Seems that the error "The driver being installed is not validated for this computer" was about a "Customized computer manufacturer driver" that doesn't allow me to update the drivers. I just had to hard replace it with the official driver in a more manually way and now all it's working just fine :)

Oh, Also I experimented today another kind of visual bug really really weird that almost make the mesh disappear completely (by random parts and without glitch or cubes) rotating around it and then I had to click to see it again, but later then it worked again as it should... so sure is caused by the same thing I think but I just wanted to mention it if there are more reports about it

Cool, thanks, here it is: ☺

Yeah running with --debug-gpu-force-workarounds fixes it, thank u much! But why it only affects the cubes? Is something really weird for me even if it's caused by an intel driver. Sorry, where can I find that file? I search for all files but no result... there's a way to generate it or something like that?

Hey, are you sure is about my GPU? No one having this issue? because this is quite annoying and so much specific things related with Blender itself, also I don't have any problems with other softwares. Just see the video and read this.....

@Clément Foucault (fclem) Tried to download that version according to my system specifications but it doesn't let me to install saying something like is not valid with my system lol and I have a very recent version of Windows 10 (1903) that looks compatible with that driver, also the official driver assistant of intel says that my software is updated :/ that's very annoying.... (want to break some windows now...)

Kinda crazy but "cool".... looks like it's weirdly pussing out the 'blob' that suffer a "compression", playing with dots...

Yeah, I confirm this is happening!

That's really weird... Just wonder if I'm the only one of the community having this issue hmm everything in Blender is stable for me but User preferences... idk what's going on. Can be something from my computer or? (This is from.. just now with last windows 64bits version)

Does it also crash if you have the preferences editor in the main window (eg. switch main 3d viewport to preferences), rather than opening from edit->preferences?
