I got a new GPU (AMD Sapphire RX 550) and since then, Blender (2.91.0) doesn't display my Objects correctly in the Viewport, while I´m in Material Preview / Rendered mode. It seems like the Materials are not there / can´t be rendered. While I´m in the Shading tab my Object looks like the Background (maybe its invisible?) and as soon as I start rotating around it does not clear the Background from the Object (like those Object smearing effect in (buggy) games when the skybox is not cleard) I tried switching the Renderer but that didn´t work.
I don't know why but now, when i go in material preview or rendered (in solid mode it works fine), my object is entirely gray, or invisible idk, because it has the same color of the background. I've been working for days on this project without having this issue, it suddenly showed up. I tried opening other old projects and suddenly they all do the same so i guess it is some blender program setting that applies for all the projects, but idk how it happened cuz i didn't change anything :/, anyone got any tips?
True Definition of the Real Numbers I've found lots of resources that say this is a real number if it's not rational, but what is a real number, really?  I mean what is the definition of a real number?  If nothing else, anyone know of a resource where I could find out myself?  Thanks! Is there a good reason to use "printf" instead of "print" in java? I'm confused, does the absorption and emission determine the color of something? Or does that only happen when something is emitting energy?  When light hits an object, the photons get absorbed, then emitted with a different wavelength right? Put a where clause around a stored procedure I cannot edit Why is the space between words in my source code listing so big? I used the following code to list my java code, but the it looks like there's too much space between words. What can I do?  % source code listing \usepackage{listings} \usepackage{color} \usepackage{xcolor}  \usepackage{caption}  % citation style \usepackage{apacite} \DeclareCaptionFont{white}{\color{white}} \DeclareCaptionFormat{listing}{\colorbox{gray}{\parbox{\textwidth}{#1#2#3}}}  \begin{document} \begin{lstlisting}[label=some-code,caption=bind to service call] bindService(new Intent(this, Recognizer.class), recConnection, Context.BIND_AUTO_CREATE); \end{lstlisting} \end{document}   The snapshot of what I got. The code not completely shown, and space too wide, in function bindService. Eevee - Light inside a bulb lamp not passing through glass Using Eevee, I'm trying to simulate a light bulb. I have a sphere with glass material and inside it, I have a Point light. But the light is not passing through the glass:  However, if I disable the sphere object, the light is working:   How to make the light inside a bulb lamp pass through glass (using Eevee)? Here my test project: How do you return 1 value per row of the max of several columns:  TableName  [Number, Date1, Date2, Date3, Cost]   I need to return something like this:  [Number, Most_Recent_Date, Cost]   Query? Named Credentials - Merge Fields not Resolving Setting Boundaries around city in google maps Should black holes be considered two-dimensional or three-dimensional? java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config Everytime, I read about blackbody, I always get confused at the point where it is written     Under thermal equilibrium conditions , the blackbody radiation depends only on temperature. ..... . At equilibrium , electromagnetic waves bounce around with the walls of the cavity.   What is this equilibrium all about? Why is it important here?? If there is thermal equilibrium, why does the body radiate?? Please help. QGIS 2.0 - can't select items in Print Composer Are there any Combinatoric proofs of Bertrand's postulate? I feel like there must exist a combinatoric proof of a theorem like: There is a prime between $n$ and $2n$, or $p$ and $p^2$ or anything similar to this stronger than there is a prime between $p$ and $(\prod_p p) + 1$ (Euclid's theorem).  I was trying to prove one by the Sieve on this grid      1     2     3     4 ... p   p+1   p+2   p+3   p+4 ... 2p  2p+1  2p+2  2p+3  2p+4 ... 3p ........................... ........................... ........................... p^2 p^2+1 p^2+2 p^2+3 p^2+4 ...   but it did not work.  Do any good arguments like this exist? I don't expect anything as strong as Prime Number Theorem or even Bertrand, but surely a direct combination proof can prove that there are lots of primes? Why would the First Order have lightsaber-resistant batons? In The Force Awakens there is a new Stormtroopr who is equipped with a lightsaber-resistant baton.    Except for one thing:   In Revenge of the Sith, most of the Jedi are killed. During the original Star Wars trilogy the last few remaining Jedi — except for Luke Skywalker — die.     And before The Force Awakens Kylo Ren kills off everyone at Luke’s school and drives Luke into exile.    There are practically no lightsabers in existence, so why are these weapons deployed at all if their only use is in counter-lightsaber combat? Defining my own None-like Python constant For some tests in R, there is a lower limit on the  calculations of $2.22 \cdot 10^{-16}$. I'm not sure why it's this number, if there is a good reason for it or if it's just arbitrary. A lot of other stats packages just go to 0.0001, so this is a much higher level of precision. But I haven't seen too many papers reporting $p &lt; 2.22\cdot 10^{-16}$ or $p = 2.22\cdot 10^{-16}$.   Is it a common/best practice to report this computed value or is it more typical to report something else (like p &lt; 0.000000000000001)? Why does default auto.arima stop at (5,2,5)? How is voltage always able to increase, if electrons move at the speed of light? Are security.ubuntu.com updates eventually merged into normal updates? Upon my observation, seems new packages will first appear in security.ubuntu.com, but if you upgrade later, they will appear in XX.archive.ubuntu.com (depends on your config),  Was that true ?
