I switched my virtual machine settings to VNC with Cirrus graphics and now the cursor is right on spot when drawing a single-pixel-dot in gimp. Unfortunately there seems to be some graphics corruption, though: the color select is a series of black-and-white lines instead of colors. Created attachment 761407 [details]
stars drawn in gimp
I used Gimp and the Pencil tool to draw a 25-pixel star stencil. I did it with both Spice/QXL graphics and with VNC/Cirrus graphics for the virtual machine.
I took screenshots showing the star and the mouse cursor, then I scaled the screenshots to double-size and cropped it to just the star and cursor.
You can see the top star -- with Spice -- the cursor is a little down-and-right from the center of the star. But the bottom star -- with VNC -- the cursor is dead-center in the star.
This may be unrelated, but I'm also seeing missing letters in Anaconda when I install with Spice/QXL graphics, but it works ok with VNC. See bug 974198 This appears to be related to recent changes to add KMS support to the qxl driver. I booted my virtual machine with "nomodeset" and the mouse clicks are where they're supposed to be now, right at the tip of the cursor. Booting with nomodeset also appears to fix bug 974198, the missing text in anaconda)! I noticed this in my /tmp/X.log (from anaconda environment): [ 14.230] qxl_kms_surface_create: Bad bpp: 1 (1) [ 14.231] qxl_kms_surface_create: Bad bpp: 1 (1) [ 14.231] qxl_kms_surface_create: Bad bpp: 1 (1) This error comes from a recent commit to the qxl driver: qxl: add KMS support v1.2 http://cgit.freedesktop.org/xorg/driver/xf86-video-qxl/commit/?id=3e37b2c And this is what gave me the idea to try booting with nomodeset I won't get this fixed for F19 GA, but I'm working on having fixes soon after, it needs a few new interfaces to pass information from the user driver to the kernel driver. this should be fixed in f19 now, reopen if not. I just built a fresh F19 VM with all the latest updates and I still have the problem. Host: kernel-3.11.1-200.fc19.x86_64 libvirt-1.0.5.5-1.fc19.x86_64 virt-manager-0.10.0-1.fc19.noarch virt-viewer-0.5.6-1.fc19.x86_64 xorg-x11-server-Xorg-1.14.3-1.fc19.x86_64 Guest: kernel-3.11.1-200.fc19.x86_64 xorg-x11-drv-qxl-0.1.1-0.11.20130514git77a1594.fc19.x86_64 xorg-x11-server-Xorg-1.14.3-1.fc19.x86_64 I verified that this issue still exists with current F19 updates, but there's an update coming that fixes it: https://admin.fedoraproject.org/updates/FEDORA-2013-23510/xorg-x11-drv-qxl-0.1.1-3.fc19 I can't edit the update to track this bug, so I'll just close as CURRENTRELEASE. Please reopen if that package in the guest (and a reboot) doesn't fix the issue. |
Created attachment 761400 [details] screenshot of gimp Description of problem: The mouse cursor on Fedora 19 TC3 in a virtual machine is off by about 3 pixels horizontally and 2 pixels vertically. I.E., if you click on x,y, it registers at x-3,y-2. In the attached screenshot, I used Gimp to draw a 1 pixel dot and you can see where it was drawn relative to the mouse cursor. This seems like a minor problem, but I noticed it because the scroll bars in Gnome Shell are rather narrow with the Adwaita theme, so if I click near the left edge of the scroll bar, it doesn't scroll but instead sends the click to the window. I hit this in Anaconda when trying to scroll through the package groups. I tried to scroll down the list but instead it selected the Cinnamon Desktop. This does not happen on Fedora 18 in a virtual machine. Version-Release number of selected component (if applicable): Fedora 19 TC3 xorg-x11-drv-qxl-0.1.1-0.8.20130514git77a1594.fc19.x86_64 libvirt-1.0.5.2-1.fc19.x86_64 virt-manager-0.10.0-0.5.gitde1695b2.fc19.noarch virt-viewer-0.5.6-1.fc19.x86_64 How reproducible: every time Steps to Reproduce: 1. install Fedora 19 TC3 in a virtual machine on a Fedora 19 host using Spice graphics and a USB tablet (the defaults) 2. start a gnome-terminal and run "ls /usr/bin" 3. move mouse to left half of gnome-terminal scrollbar and try to click 4. start Gimp and use the Pencil tool to draw a 1 pixel dot Actual results: the cursor is an I shape for selecting text and cannot scroll dot in Gimp is a few pixels away from the mouse cursor Expected results: the cursor changes to an arrow and lets you scroll dot in Gimp is directly under the tip of the arrow cursor Additional info:
